CHAPTER 1

HANDBOOK ORGANIZATION AND CONTENT

1.0 OVERVIEW

The format of the Damage Tolerant Design Data Handbook has been modified

slightly since the previous update in 1983. Data are still presented in material

chapters and sorted by alloy within the chapters. Available alloy property data are

then presented in a consistent order from chapter to chapter. This organization was

suggested by aerospace engineers as the format best suited for their use.

Additionally, this format conforms to other aerospace structural metals handbooks

such as the Military Handbook-5 and Aerospace Structural Metals Handbook.

A survey was conducted at the beginning of this handbook program. A number

of aerospace design, materials, and structural engineers were canvassed for their

comments relative to the handbook organization, formats, summaries and data types.

It was agreed that the overall format of the 1983 edition of the handbook was

generally acceptable. The page numbering scheme in the 1993 edition transitioned

to sequential page numbers within chapters to facilitate looking up alloy data. The

table of contents on the first page of each material chapter lists the alloys in the

chapter along with their starting pages.

Mean trend fatigue crack growth and sustained crack growth data are now

listed on the same page as the plots of their crack growth rate data. If available, the

root mean square percent error and life prediction ratio for these data are also listed

on the same page. This new format removes confusion about the relationship of crack

growth data to their fitted mean trend data.

Data are presented in English units throughout the handbook, i.e., KsiVin for

fracture toughness and applied stress intensity factor levels, and inches/hr or

inches/cycle for crack growth rates. Metric units have been incorporated along with

1-1


the English units on the graphical presentation of the sustained load and fatigue

crack growth rate data, but limited space forced the exclusion of metric units from

the tabular data.

1.1 ORGANIZATION

The handbook is divided into eight chapters and consists of five volumes. The

order of the chapters are as designated in Table 1.1. Following the first chapter on

handbook usage and the second chapter on methods of calculations are the six

material chapters. This order was selected to keep the data for a particular chapter

together as much as possible while keeping the volume sizes reasonable and

approximately equal.

subsection, table or figure number refers to the material chapter as specified in Table

1.1. A zero in the second position indicates that the data is a material summary.

Consecutive sequence numbers originating at one are assigned to alloys as the second

number in the numbering scheme. The alloy sequence numbers are defined On the

index page of each material chapter. The material bibliography is assigned the

sequence number immediately following the last alloy in the material chapter.

In the material summary section, CO..., where C represents a material chapter

number, five types of material summary tables may be listed as subsections. Tables

will be listed in the order defined by Table 1.2. If, however, not enough data are

available for a particular summary, this summary is not printed and its sequence

number is skipped. Section 1.3 describes the formats for material summaries.

In the alloy section, CA..., where C represents material chapter number and

A represents alloy number, the third number in the sequence will designate whether

the data are an alloy summary (C.A.1), fracture toughness data (C.A.2), or crack

growth resistance data (CA.3). Within each subsection, data tables and graphs are

ordered consecutively. If, however, insufficient data are available to generate a table

or figure, the table or figure in question does not appear and the sequence number

is skipped.

Section 1.4 discusses the formats of two alloy summaries: plane strain fracture

toughness and fatigue crack growth rate. Section 1.5 discusses the data formats of

three types of fracture toughness data: plane-strain fracture toughness, plane stress

and transitional fracture toughness, and resistance curve. Section 1.6 discusses the

data formats of three types of subcritical crack growth data: fatigue crack growth

rate, sustained load crack growth rate, and stress corrosion cracking threshold.

To help the handbook user locate data, examples of actual tables and figures

are included in the discussions of the handbook subsections which follow. These

examples are presented to familiarize the user with the formats presented in the

handbook. The discussion follows the same order as that found in the handbook.

1.2 DATA ORDERING AND ABBREVIATIONS

1.2.1 Sorting Order

Data fields in the handbook database exist in one of three formats:

text, numeric, or coded. The ASCII (American Standard Code for Information

Interchange) collating sequence (Table 1.3) defines the sort order for text fields such

as alloy, condition/heat treat, and environment. Letters are case insensitive in text

fields, i.e., lower case letters are treated as their upper case equivalents. Numeric

fields are presented in ascending order (most negative to most positive). Test

temperature is a numeric field that has a minor exception in that temperatures from

65°F to 80°F are grouped as room temperature and are considered equal. Coded

fields are ordered on their code value according to the ASCII collating sequence.

Table 1.4 presents three such coded fields: product form, specimen design, and

specimen orientation. Existing codes and their equivalent values are given in coded

order. Note that the equivalent values are used in the presentation of material data.

1.2.2 Abbreviations

The material chapters present tables and figures summarizing material

property data. Abbreviations are used throughout the tables and figures in these

chapters for the following five data fields: 1) condition/heat treatment, 2) product

form, 3) environment, 4) specimen design, and 5) specimen orientation. Abbreviations

and expanded descriptions used in the presentation of these data types can be found

in Tables 1.5 through 1.8 and Figure 1.1, respectively.

1.3 MATERIAL CHAPTER SUMMARIES

Material summaries are presented at the beginning of each chapter before alloy

summaries and detailed data. These summaries are meant to aid in comparing

material properties and selecting materials for design. There are five data types (see

Material Summaries in Table 1.2) for which material summaries are possible. Each

summary compares availability or properties of damage tolerant data for the given

alloys, heat treatments, and product forms of a particular material.

1.3.1 Available Data Summary

Figure 1.2 presents the fourth page of the available data summary for

Aluminum 7000/8000 labeled as TABLE 8.0.1. The first number in the table number

is "8" which indicates that this table belongs to the eighth chapter; the second

number is "0" which indicates that this is a table in the material summary section.

The third number is "1" which indicates that this is the "Available Data" table for

this material.

The available data summary defines the property data that are

available in a chapter by alloy, condition/heat treatment, and product form. The

number is each data type cell in Figure 1.2 indicates the number of test specimens

recorded in the handbook database for the specific test conditions of alloy, heat treat,

and product form. The six different types of data are listed across the top of the

table. Alloys are listed in ASCII collating sequence which is how they appear in the

handbook. Heat treatments and conditions are also sorted according to the ASCII

collating sequence. Following the sort by alloy and condition/heat treatment, the

property data are then sorted according to product form. Product form sort order is

outlined above in Table 1.4.

1.3.2 Plane Strain Fracture Toughness Material Data Summary

Figure 1.3 presents the second page of the aluminum 7000/8000 plane-

strain fracture-toughness data summary labeled as TABLE 8.0.2. This is the second

type of material summary and its third table digit is "2". Data are sorted and

grouped by alloy, condition/heat treatment, and product form. Data are listed only

for specimens tested in laboratory air at room temperature (65°F - 80°F). Plane

strain fracture toughness values and standard deviations mean are listed for the

three most frequently occurring specimen orientations; i.e., L-T, T-L and S-L.

Product thickness range and minimum specimen thicknesses are listed for general

information. Dashes in a particular column indicate that no mean plane strain

fracture toughness data exist for the stated conditions.

1.3.3 Plane Stress and Transitional Fracture Material Data Summary

The plane stress and transitional fracture toughness data summary is

presented third in the series of summaries. Two tables may be presented for a

material type if sufficient data are available. The first table (Figure 1.4a) presents

test data for specimens where buckling constraints were not imposed. The sequence

number for this type of table is C.0.3.1, where C is the material chapter number. The

second table (Figure 1.4b) presents test data for specimens where buckling

constraints were applied. The sequence number of this table is C.0.3.2, where C is

the material chapter number. The third digit of the table number is always "3".

Observe that the fourth digit is "1" and "2" for test specimens without and with

buckling constraints, respectively. The data are sorted in both table types by alloy,

condition/heat treatment, test temperature, specimen orientation and specimen width.

Yield strength is not a sorting field but is included for general information. Mean K,.

values are listed as a function of specimen thickness which is indicated across the top

of the page. Specimen thickness variations run along the top of the page and may

vary from table to table to prevent overcrowding in the tables while still

accommodating all of the data. Individual K,, data values are listed only if useful in

determining a trend in the data.

1.3.4 Fatigue Crack Growth Rate Material Data Summary

Figure 1.5 presents a sample fatigue crack growth rate (FCGR)

summary taken from the Aluminum 7000/8000 Chapter. The data are from Table

the chapter (8) and the summary section (0). The third number in the sequence (4)

indicates that this is an FCGR summary table. The fourth number in the sequence

(2) indicates that this is the second ordered table in the fatigue crack growth rate

summary for a given material. When only a single FCGR summary table is available

for a material, the fourth number in the sequence is dropped. Readers will find one

table for each specimen orientation for which there are enough data for the table to

have meaning.

All data in a particular summary table were collected under conditions

where the environment is laboratory air at room temperature. The stress ratio and

loading frequencies vary slightly depending on the individual tests. The range of test

conditions are listed at the top of each table. Beneath the general description of test

conditions are the data fields of alloy, condition/heat treatment and product form for

which the FCGR data comparisons can be made. Predefined AK levels are listed

across the top of the table and are a subset of the levels associated with the tabular

format of the mean trend FCGR data. See Section 1.6 for a list of all predefined

mean trend AK levels. Fatigue crack growth rates expressed in 10"6 inches/cycles are

listed in the applicable columns and rows according to the alloy, condition/heat

treatment, and product form. With this format, it is easy to determine which

materials, heat treatments, or product forms have the lowest growth rate at a

particular AK level.

1.3.5 Stress Corrosion Cracking Threshold Material Data Summary

Figure 1.6 illustrates the stress corrosion cracking threshold material

data summary - the fifth possible material data summary. The sequence number

assigned to this table type is C.0.5, where C is the material chapter number. Because

of the small number of specimens (typically one or two) that are used to generate

these data, individual results are presented here rather than means and standard

deviations. The data are sorted by alloy, condition/heat treatment, product form and

specimen orientation. Possible environments for which KIscc data exist are listed

across the top of the table. Kiscc data values for each particular environment are

listed in the appropriate row and column. This table summary allows for

comparisons of KIscc values of various materials in a particular environment as well

as a quick assessment of how various environments affect a particular material.

1.4 ALLOY SECTION SUMMARIES

Following the material summaries, the data are divided into sections by alloy.

Each alloy section is further divided into three subsections: a data summary

subsection, a fracture toughness subsection, and a crack growth resistance subsection.

The data content and format for these three subsections are described in this and the

following two subsections, respectively.

There are two possible alloy summaries: a plane strain fracture toughness

summary and a fatigue crack growth rate data summary. Tables in these summaries

are labeled C.A.1..., where C is the material chapter number, A is the alloy section

number, and "1" identifies the alloy summary section. A fourth number appears on

each table in this section. The numbers "1" and "2" in the fourth position indicate

plane strain fracture toughness and fatigue crack growth rate, respectively. A fifth

number is appended to the fatigue crack growth rate table number when multiple

tables exist for an alloy.

Figure 1.7 presents the tabular format for the KIc alloy summary. It is similar

to the KIc material summary in that the mean and standard deviation for a particular

condition/heat treatment, product form, and specimen orientation is given for each

alloy. However, the number of specimens used to generate the data has been added.

The data are sorted by product form, condition/heat treatment, and specimen

orientation. This summary groups KIc data by condition and product form for easy

comparison. It also allows for quick assessment of the effect that orientation has on

fracture toughness.

Figure 1.7 Sample Table (pg 8-452): Mean Plane Strain Fracture Toughness at Room Temperature (Alloy Summary)

1-22


The FCGR alloy data summaries shown in Figure 1.8 are similar to the FCGR

material data summaries described previously. Note that for a particular alloy, the

data are separated by the test variables of specimen orientation and environment

which are listed at the top of each page. The sort order of specimen orientation is

shown in Table 1.4 and environment is sorted alphabetically. Other test variables

such as condition/heat treatment, product form, stress ratio and frequency are then

listed for the data as noted. Typically, a number of FCGR data summaries are

produced to describe the effects of specimen orientation and environments. The

condition/heat treatment and product form yielding the lowest crack growth rate in

a given environment for a given specimen orientation may be determined from these

summary tables. Discrepancies in data sets can also be noted as well as a quick

determination of how stress ratio and frequency affect the crack growth in a

particular environment.

1.5 ALLOY FRACTURE TOUGHNESS SUBSECTION FORMATS

Within each alloy section following the alloy summaries is the fracture

toughness type data. Fracture toughness data consist of plane strain data (KIc), plane

stress and transitional fracture toughness data (K,), and resistance curve data (R-

curves). Each of these has a different and yet somewhat similar ordering scheme

which is particularly suited to that type of data. Tables and figures in these sections

are labeled C.A.2..., where C is the material chapter number, A is the alloy section

number, and "2" indicates the fracture toughness section. A fourth number appears

on each table and figure. The numbers "1", "T, and "3" in the fourth position indicate

KIc, K,, and R-curve, respectively. KIc and K, tables may have multiple pages. Page

sequence numbers are given to the upper right of each table. A fifth number is

assigned to R-curve plots when multiple plots are available for an alloy.

1.5.1 Plane Strain Fracture Toughness Data

The format for the plane-strain fracture toughness data is shown in

Figure 1.9. This particular example is taken from the aluminum 7000/8000 chapter

for alloy 7075. The data are sorted by condition/heat treatment, product form, test

temperature, orientation and yield strength using the primary sort order identified

in Section 1.2.1. KIc data collected for similar test conditions are grouped together

with the mean and standard deviation listed in a column near the right of the page.

Product thickness is listed after product form, but is not a sorting parameter.

Specimen dimensions (thickness and width) and crack length are also listed, but not

sorted in any particular order. The 2.5(KIc/cys)2 criterion value is included for

information purposes only. Two additional columns list the date of the reference and

the reference number so that when and where the data were collected can be

assessed, and where additional information might be obtained should it be desired.

Footnotes may be given as a number enclosed in parentheses behind the reference

number. Footnotes are used to indicate out-of-range conditions, average data values,

and other important identifying features.

Reference numbers from the earlier versions of the handbook have been

retained and new data have been assigned a new reference number with the first two

or three characters identifying the organization or journal from which the data was

obtained. Table 1.9 lists the general format for later reference numbers.

1.5.2 Plane Stress Fracture Toughness Data

The format for presenting plane stress fracture toughness (K,.) data is

presented in Figure 1.10. Plane stress fracture toughness data within a particular

alloy section are ordered by condition/heat treatment, buckling of crack edges

(restrained, unrestrained, or unknown), product form, test temperature, specimen

orientation, specimen thickness and specimen width. Additionally, initial and final

crack lengths are given as a function of the total crack length (2a) for center-cracked

panel specimens. Also, the onset and maximum gross stress values are listed when

available. The fracture toughness parameters K,. and K^ are calculated as described

in Chapter 2 and the individual as well as the mean and standard deviation values

are listed for both K,. and K^. The final two columns present the date of the

reference and the reference number.

1.5.3 R-Curve Data

The format for resistance curve (R-Curve) data is shown in Figure 1.11.

The information listed at the top of the page includes alloy, condition/heat treatment,

product form, product thickness (if known), specimen design, specimen orientation,

specimen dimensions (thickness and width), K^ value (if known), and reference

number. Unless otherwise specified, the data were tested at room temperature in

laboratory air environments. Only one specimen is illustrated per figure, and the

figures are sorted by alloy, condition/heat treatment, test temperature and

environment, specimen orientation, specimen thickness, and specimen width.

Resistance curve data are plotted on linear axes with applied stress intensity KR

(KsiVin) as a function of change in effective crack length Aaeff (in.). Section 2.4

contains details associated with the R-curve calculation.

1.6 SUBCRITICAL CRACK GROWTH SUBSECTION FORMATS

The subcritical crack growth data follow the fracture toughness data within

each alloy section. The subcritical crack growth data includes: fatigue crack growth

rate data, sustained load crack growth rate data, and stress corrosion cracking

threshold data. Figures and tables in these sections are labeled C.A.3..., where C is

the material chapter number, A is the alloy section number, and "3" indicates

subcritical crack growth sections. A fourth number appears on each figure and table.

The numbers "1", "2", and "3" in the fourth position indicate fatigue crack growth

rate, sustained load crack growth rate, and stress corrosion cracking threshold data,

respectively. Both the fatigue and sustained load crack growth rate figures have a

fifth number when multiple plot sets exist for an alloy.

1.6.1 Fatigue Crack Growth Rate Data

Fatigue crack growth rate data are presented in two complementary

formats: graphical (data points overlaid with a mean trend curve) and tabular (listing

of mean trend data points). The data on a page describe the effects of one of three

varying parameters - stress ratio, environment/test temperature, or frequency. A

header window lists parameter values which are considered constant for all test data

being presented. Plots for two values of the varying parameter can be presented on

a given page. Multiple pages are used to present plots for three or more values of the

varying parameter. In addition to the da/dN-AK plots and mean trend tables,

minimum and maximum AK, root mean square percent error, and life prediction ratio

of the mean trend curve are given when available. All plots having similar header

data are subsequently referred to as a plot set.

Figure 1.12 shows an actual page of fatigue crack growth rate data

from the handbook. Each page consists of five data block types: 1) header block,

2) FCGR plot block, 3) mean trend block, 4) root mean square (RMS) block, and 5) life

prediction ratio (LPR) block. The header block is common to the plot set. Data block

types 2 through 5 are specific to one value of the varying parameter.

The header block identifies the alloy, the varying parameter, and

constant values for all plots in the current plot set. The alloy is identified in the

upper outside corner of the plot page. The varying parameter is also identified in the

upper outside corner by the presence of the capital letters "R" (stress ratio), "E"

(environment), "F" (frequency), or "EF" (combination of environment and frequency).

Environment is the varying parameter in Figure 1.12. Condition/heat treat, product

form/thickness, specimen type, specimen orientation, tensile yield and ultimate

strengths, specimen thickness, specimen width, and references always appear in the

header block if available. Stress ratio, environment, and frequency are also listed in

the header block when they are not the varying parameter. Values of certain

constant parameters are given as ranges when the values are close enough to be

considered similar.

The FCGR plot block consists of the following four items: 1) a trend

plot of da/dN-AK data, 2) the value of the varying parameter, 3) a mean trend curve

(if available), and 4) the plot set sequence number. Fatigue crack growth rate (da/dN)

is plotted as a function of the range of stress intensity (AK). The definition of AK

according to ASTM Standard E647, i.e., AK = K^ if stress ratio is negative, was

chosen for data presentation throughout the handbook. The logarithmic x-axis

represents AK and spans from 1 to 200 Ksh/in. The logarithmic y-axis represents

da/dN and spans 7 decades from 10"8 to 10'1 inches/cycles. English units, i.e.,

inches/cycle for da/dN and KsiVin for AK, are listed to the left and bottom of each plot

respectively. The corresponding metric units for da/dN and AK, i.e., mm/cycle and

MPaVm, respectively, are placed on the opposite side of the plot as their English

counterparts.

The trend plots in Figure 1.12 indicate that multiple plot symbols may

be used. Each symbol represents a unique set of test data. Up to eight different

tests can be accommodated in a single plot. If more than eight tests have common

header data, then additional plots are generated. Each plot uses the same plot

symbols; however, the data they represent are independent from plot to plot. If eight

or more data points exist, a mean trend curve is fit to the plotted data using a cubic

spline polynomial. The cubic spline polynomial fit method is described in

Section 2.5.4.

The sort order in which fatigue crack growth rate data are presented

is as follows: alloy, condition/heat treat, product form, product thickness, specimen

design, and specimen orientation. The ordering by product form has been revised so

that similar product forms such as extruded bars/extrusions and forged

bars/forgings can be presented next to each other. Table 1.10 presents the revised

sort order of product form. Table 1.4 above presents the sort order of specimen

design and specimen orientation.

Given that certain test data have similar values for the above

mentioned parameters, individual plots in a plot set are presented in order by varying

parameter. Plot sets varying stress ratio are placed before plot sets varying

environment which in turn are placed before plot sets varying frequency. For varying

stress ratio, plots are presented in ascending stress ratio order. When environment

is the varying parameter, plots are presented in alphabetical order on environment

and ascending test temperature. For varying frequency, plots are presented in

ascending frequency order.

The mean trend window presents fatigue crack growth rate values

calculated at predefined AK levels based on the cubic spline polynomial curve fit to

1-34


the test data. Table 1.11 lists the 30 possible AK levels for which corresponding da/dN

crack growth rates may be calculated. The minimum and maximum AK values

observed in the test data are included and delimit the range of predefined AK levels

to be included in a mean trend table. If less than eight data points are available, the

mean trend window is empty.

TABLE 1.11

100. 130. 160. 200.

The RMS data block presents root mean square percent error (RMS %

Error) which is a description of scatter about the mean trend line; i.e., a smaller

value indicates less scatter than a larger value. The RMS block is empty if a mean

trend cannot be generated. The calculation of the root mean square percent error is

described in Section 2.5.4.

The LPR data block reports the life prediction ratio for specimen test

data plotted in the plot block. The LPR is the number of cycles predicted using the

mean trend curve divided by the actual number of cycles taken from the experimental

crack length versus cycle (a-vs-N) data for a predefined interval. Plot symbols are

placed along a scale ranging from zero to two with intermediate tic marks at 0.5, 0.8,

and 1.25. The plot symbol placed along the scale is the same plot symbol used to

represent a specimen test in the trend plot above. LPR values which fall between 0.8

and 1.25 indicate an adequate mean trend fit. For threshold type tests and for tests

in which the loads were varied frequently during the test, LPR values tended to be

well outside this range. Some test data shown on the trend plot do not have a

calculated LPR value because the data were received in reduced form, i.e.,

da/dN-vs-AK rather than a-vs-N, and therefore had no actual cycle count for

comparison. If a mean trend fit cannot be generated, no plot symbols appear in the

LPR data block.

1-35


1.6.2 Sustained Load Crack Growth Rate

The sustained load crack growth rate data are presented after the

fatigue crack growth rate data and are plotted on log-log scales in a manner similar

to the FCGR data (See Figure 1.13). The data are plotted to present time based crack

growth rate as a function of maximum stress-intensity factor on pages with header

blocks and two graphs of equal size with both English and Metric units lining

opposite sides of the plot. The alloy is identified in the upper outside corner of the

plot page. The condition/heat treatment is listed at the very top of the header block

and the remaining parameters are listed in two columns beneath the condition. The

first column contains the parameters of product form and thickness, specimen type,

specimen orientation, tensile yield strength, and tensile ultimate strength. The

second column contains specimen thickness and width, initial crack length (a,,), stress

corrosion cracking threshold value KIscc, and reference numbers. There are also three

variations on these plots, that is, variations on product form and product thickness,

tensile yield strength, and test temperature/environment. There are also some data

sets in which condition/heat treatment for a given alloy is varied. In addition to the

three basic plot variations noted, the sustained load crack growth rate data have two

possible growth rate axes in order to accommodate the data. Both axes span six

decades. The first axis ranges from 10'6 to 1 inches/hour, the second 10"4 to 102

inches/hour (English units). Both have maximum stress-intensity (K^) values that

range from 1 to 200 KsrVin. The corresponding metric units for da/dt and K^, i.e.,

mm/hour and MPaVm, respectively, are placed on the opposite side of the plot as

their English counterparts.

Some of these data also have mean trend curves and mean trend tables

associated with them. The mean trend tables are presented directly beneath the

graphical presentation of the data in a manner similar to the fatigue crack growth

rate data. The format of the table in Figure 1.13 is nearly identical to that of the

fatigue crack growth rate data. Since all sustained crack growth data were received

in reduced form, the LPR cannot be calculated. Therefore, LPR has been omitted

from the plot page. Due to the nature of the data, the values of the RMSPE are

usually larger than those of the FCGR data. Additionally, mean trend curves

representative of the data are not always created. For these cases, no mean trend

curve or table is presented.

1.6.3 Stress Corrosion Cracking Threshold

Following the sustained load crack growth rate data is the tabular

stress corrosion cracking threshold data. An example of this data format is presented

in Figure 1.14, which is similar to the fracture toughness data format. The material,

alloy and data type are listed in the table title. Condition/heat treatment, product

form, product thickness, test temperature, specimen orientation, yield strength, and

environment are listed in the table from left to right. Following these parameters are

the specimen design, width and thickness as well as product thickness, crack length,

KQ fracture toughness, KIscc individual values, test times, dates and reference

numbers. The data are sorted by alloy, condition/heat treatment, product form, test

temperature, specimen orientation and environment.

The fracture toughness value KQ indicates the level of crack toughness

of the material. These values were obtained from threshold tests and are not valid

plane-strain fracture toughness values. The KQ values, however, should provide an

engineer with an indication of stress-corrosion cracking sensitivity relative to

fracture.

In the KIscc tabular data, the specimen design column and/or the KIscc

column may be footnoted. An asterisk appearing in the specimen design column

indicates that the specimen has been side-grooved along the path of the crack. A plus

sign appearing in the KIscc column behind the individual KIscc values indicates that the

crack length and/or specimen thickness were not greater than the required minimum

value of 2.5(ü:/scc/a^)2.

CHAPTER 2

METHODS OF CALCULATIONS

2.0 OVERVIEW

This chapter briefly describes the methods used to calculate the damage

tolerant properties reported in the Handbook. The properties reported for

characterizing fracture resistance include:

KIc, the plane-strain fracture toughness

K,., the critical plane-stress (or transitional) fracture toughness

KApp, the apparent plane-stress fracture toughness

KR, the tearing resistance

and, the properties reported for characterizing subcritical crack growth resistance

include:

- , the constant amplitude fatigue crack growth rate dN

j

- —, the sustained-load crack growth rate dt

- KIscc, the threshold for sustained load cracking

Sections 2.1 through 2.7 describe these properties and the specific methods of

calculations utilized to convert laboratory (specimen) data into the properties

reported.

2.0.1 Data Review and Acceptance Criteria

Newly acquired data and data available from previous revisions of the

Handbook were systematically reviewed and analyzed. The principal data acceptance

2-1


criteria were based on criteria established by the American Society for Testing and

Materials (ASTM); these criteria are embedded within ASTM standards for test

methods and practices. Table 2.1 lists those standards used to provide criteria for

plane-strain fracture toughness (Klc) data, for R-curve data, and for fatigue crack

growth rate (da/dN) data. ASTM literature was also reviewed to establish criteria

based on typical engineering practice for the other types of data collected and

reported.

Newly acquired data was substantially easier to process than the data

available from previous revisions since the data suppliers screened their data

according to ASTM criteria before it was released to the data processing organization

(UDRI). Also, when questions concerning newly acquired data developed, the

suppliers could be called and the questions resolved.

The final step in the review process was the determination of whether

the data were a "true" representation of the behavior they described. This step was

implemented for both newly acquired data as well as for the available Handbook data

in order to eliminate suspect data through subjective criteria. Unfortunately, it is not

possible to detail the subjective criteria that were employed to exclude questionable

data. It can be stated that the principal mode of operation here was by way of

comparison between behaviors that were expected to be somewhat similar.

2-2


2.0.2 Fracture Mechanics Basis

The damage tolerant data reported in this Handbook utilize the

technology of linear elastic fracture mechanics. This technology is widely applied

throughout the aerospace industry to relate structural calculations for cracked

structures to material behavior in the presence of cracks. In essence, fracture

mechanics provides a structural parameter, the stress-intensity factor (symbol K)

which characterizes the magnitude of stresses and strains in the crack tip region of

essentially elastic structures. It was postulated that the stress-intensity factor

represents a similitude parameter that describes crack tip behavior under various

loading conditions (monotonically increasing load, fatigue loading, etc.); the

hypothesis has been verified for a wide number of materials, loading conditions, and

failure type mechanisms. For a more thorough review of linear elastic fracture

mechanics and its applications to the aerospace industry, see AFWAL-TR-82-3073,

USAF Damage Tolerant Design Handbook: Guidelines for the Analysis and Design

of Damage Tolerant Aircraft Structures.

Currently, there are developments that are extending the technology

of fracture mechanics to aid in the solution of crack problems for which the

assumptions of linear elastic fracture mechanics are invalid. This technology is

referred to as nonlinear fracture mechanics and its similitude parameter is the J-

integral (J), or alternately the crack tip opening displacement (8). To date, nonlinear

fracture mechanics has been successfully utilized to characterize tearing type

fractures and fractures occurring in the presence of large-scale yielding. Some

evidence has been presented suggesting that J may provide a similitude parameter

for non-monotonically increasing type loadings, i.e., for fatigue loadings; but,

questions still exist here. It is expected that subsequent revisions of this Handbook

will include nonlinear fracture mechanics type data such as JIc, a plane-strain

fracture toughness property, and JR-curves, (tearing resistance curves).

2-3


2.0.3 Test Specimen Geometries

As described above, the stress-intensity factor provides a parameter

that can be used to establish similitude between two cracked structures. This means

that if the stress intensity factor in structure A equals the stress-intensity factor in

structure B and if other conditions (loading, material, environment, etc.) are the

same, then the cracks in both structures will behave the same way. This concept

provides the justification for conducting material behavior studies on small laboratory

test specimens (coupons) which contain cracks. If the resistance to cracking in the

laboratory can be optimized by a choice of material, then improved resistance can also

be obtained for structural hardware (given that the material can be fabricated into

the hardware without processing degradation taking place).

The types of test specimen geometries that have been employed to

generate damage tolerance (fracture mechanics) type data for this Handbook are

summarized in Table 2.2. Table 2.2 also guides the reader to individual figures

(Figures 2.1 through 2.14) which describe the geometries associated with individual

specimen names and symbols.

To relate the crack type data collected in a cracked test specimen to

other cracked structures, it is necessary to have a description of the stress-intensity

factor (K) as a function of crack length (a) for the test specimen geometry. A great

deal of attention has been given to generating accurate stress-intensity factor

equations for laboratory test specimen geometries, due to their importance to

standard methods of test and to reporting data. The stress-intensity factor equations

are typically presented in either of the following two forms:

(2.1) K = G yna •ß

where a = remote stress (load -f area)

a = crack length measure

ß = function of crack length and global geometry

or

K = -JL- Y (2.2) BW

where P = load

B = thickness of specimen

W = width of specimen

Y = function of crack length (a) and global geometry

Equation 2.1 is used when the loading is applied remotely from the crack, whereas

Equation 2.2 is more typically used for point loading or localized loading conditions.

One should note that K is a linear function of loading (a in Equation 2.1 and P in

Equation 2.2) and that the loading and geometric components of the equations are

independent of each other. Thus, if one wishes to describe a stress-intensity factor

relationship for a given geometry, they might formulate the equations in the following

forms:

E = VJW • ß (2.3) a

2-11


or

K = Y (2.4)

BW

Equations 2.3 and 2.4 are referred to as stress-intensity factor coefficients; the right

hand side of these equations only describes the effect of the crack in the given

geometry.

Table 2.3 provides a listing of stress-intensity factor coefficients which

were used to generate data for this Handbook. Each equation is given a stress-

intensity factor equation number, e.g., SIF.7 refers to the stress-intensity factor

coefficient for the WOL (Wedge Opening Load) specimen geometry illustrated in

Figure 2.6. Also note that Table 2.3 has a remarks section which describes the

conditions under which individual equations were used.

2.1 PLANE-STRAIN FRACTURE TOUGHNESS (Klc)

The plane-strain fracture toughness (KIc) property was initially established to

characterize the fracture resistance of materials that exhibited rather abrupt

fractures in the presence of cracks. Early observations showed that thickness had a

pronounced effect on the critical levels of stress-intensity factor associated with

fracture; a schematic illustrating this behavior is presented in Figure 2.15. As noted

in the schematic, for thicknesses greater than the experimentally determined lower-

bound, the critical stress-intensity factor level was found to be relatively constant.

The reasons for the independence of toughness with further increases in

thickness were related to the amount and type of yielding which could occur at the

crack tip under what has been referred to as plane-strain conditions. Because the

thickness-independent toughness property was useful for comparing a large variety

of metals for fracture resistance, ASTM (American Society for Testing and Materials)

embarked on a standardization effort that eventually resulted in the ASTM Standard

Test Method for plane-strain fracture toughness of metallic materials, i.e., in the

ASTM Standard E399.

The ASTM Standard E399 is the current procedure for determining critical

plane-strain stress intensity factors (KIc values) for high-strength alloys. From the

method of test, "The property KIc determined by this method characterizes the

resistance of a material to fracture in a neutral environment in the presence of a

sharp crack under severe tensile constraint, such that the state of stress near the

crack front approaches tritensile plane-strain, and the crack-tip plastic region is small

compared with the crack size and specimen dimensions in the constraint direction."

Assuming that plane-strain conditions are approximated when unstable

cracking occurs at the crack front during a KIc test, the critical stress intensity factor

calculated from the test data is characteristic of the material of the specimen at the

testing temperature and for the specific crack growth direction. Since the properties

vary somewhat from specimen to specimen in one plate or in one heat, and from heat

to heat of a given alloy type with the same heat treatment, the measured KIc values

for several heats will show some degree of scattering in the data. Usually, the extent

of scattering is greater than that for replicate tensile tests. For this reason, a

relatively large number of data points would be required to establish minimum design

values for any of the fracture mechanics parameters. To minimize the scatter in

data, maximum effort is required in controlling the processing, preparation, and

testing of each specimen. These precautions are discussed in the Method of Test

(ASTM E399).

The ASTM E399 procedure indicates that calculated K values be designated

KQ, which is a provisional value. When the validity of the results is established by

the procedures designated in the Method of Test, then the KQ value can be identified

as a valid KIc value. Some of the primary criteria for judging the validity of KIc

values are based on crack length and specimen thickness conditions. The test data

2-19


must demonstrate that sufficient constraint was available to justify the plane strain

assumptions. The other requirements for validity of the KIc values involve

measurements of the length of the fatigue crack, contour of the crack front, out-of-

plane deviation of the fatigue crack, maximum stress intensity resulting from the

fatigue cracking load, and details of the load-deformation curves.

All newly acquired plane-strain fracture toughness (KIc) data incorporated in

the 1993 Handbook revision were generated using the ASTM Standard E399. All

suppliers of new Klc data provided only E399 validated Klc data in a reduced format

which facilitated direct incorporation into the Handbook. Data incorporated in earlier

revisions for the most part utilized ASTM Standard E399 or the predecessor tentative

method for plane-strain fracture toughness testing; and after review, these data were

also included into the 1993 revision. In some instances, nonstandard specimens were

used for generating critical plane-strain stress-intensity factors in the earlier

revisions. Some of these data were incorporated in the 1993 revision on the basis

that a reasonable procedure was used and that corresponding data from other sources

were limited for the alloys concerned. All data were checked against the criteria for

specimen thickness (B) and crack length (a), i.e., B, a > 2.5 (Klc /ays)2 where ays is the

tensile yield strength.

2.2 CRITICAL PLANE STRESS FRACTURE TOUGHNESS

2.2.1 Plane Stress and Transitional Fracture Toughness

The critical level of the stress-intensity factor for non-plane-strain

conditions is normally described with the symbol K,., see Figure 2.15, and is referred

to as the plane-stress or transitional fracture toughness. Generally, plane-stress

fracture-toughness testing is representative only of through-the-thickness cracks in

relatively thin section materials. For a given material thickness, this configuration

has the least lateral restraint on the crack front and, hence, approaches most closely

the ideal plane-stress stress state conditions at the crack tip. As the material

2-20


thickness increases, transitional stress state behavior is introduced by the restraint

of additional material along the crack front. In contrast to that in plane-strain

fracture-toughness testing, the characterization of fracture toughness in the plane-

stress and transitional-stress states is complicated by the degree to which crack tip

plasticity and associated stable crack extension are manifested prior to fracture.

Although an explicit test method for this mode of toughness has not been formulated,

there are a number of useful experimental guidelines which have been developed.

As background information, the nature of plane-stress and transitional

fracture toughness is described here in terms of its deviation from that of the plane-

strain stress state. Current procedures for this mode of testing and the associated

analytical formulations of toughness then are presented.

The difficulties that beset the characterization of plane stress and

transitional fracture are not only of a theoretical nature, but also of a practical

experimental nature. Basic questions on the nature of plasticity, crack extension, and

crack instability, as well as the wide variation in experimental techniques among

laboratories all contribute to variability in the resulting fracture toughness

evaluations. However, in spite of these difficulties, surprisingly consistent

charcterizations of fracture behavior can be obtained.

During the fracture test of a structural material in a plane-stress or

transitional-stress state, stable extension of the initial fatigue precrack may occur as

the load increases. This behavior is illustrated schematically in the crack growth

curve of Figure 2.16. Depending on the material, stable crack extension may amount

to 30 percent or more of the initial precrack length.

Once it is understood that fracture under these conditions is not an

abrupt instability instantaneously associated with a small increment of crack

extension, it must also be recognized that a single toughness parameter is not

sufficient to characterize this complex behavior. In fact, the concept of crack

growth resistance

curves (see Section 2.4) is an outgrowth of these observations and best describes the

material behavior. However, as a means of characterizing fracture behavior in plane-

stress and transitional stress state, engineers have traditionally utilized abrupt

fracture concepts, i.e., have used critical stress-intensity factor levels, to describe

various events associated with the observed behavior.

2.2.2 Plane Stress and Transitional Fracture Toughness Testing

The procedures associated with testing thin-section center-cracked

tension panels differ from those associated with plane-strain fracture toughness

testing only in the additional emphasis and refinement that is directed to monitoring

the slow, stable tear portion of the fracture process.

The general testing configuration is illustrated schematically in Figure

2.17. The specimen with an initial fatigue precrack, 2a0, is loaded slowly under load

or stroke control. The onset and extension of crack growth under increasing load is

usually monitored photographically, visually, or by means of compliance gage

calibration until fracture occurs.

Although, as previously mentioned, more attention is currently being

directed to monitoring the detail stress and crack length dimensions during the slow

tear process, the majority of available test data is limited to a record of a0 or 2a0 or

Gc, and 2ac, as indicated in Figure 2.16. It is this information which is compiled and

analyzed in this Handbook.

2.2.3 Critical Stress-Intensity Factor (K,.)

There are two clearly identified points that can be noted on the crack

growth resistance curve shown in Figure 2.16, i.e., points O and C which are associ-

ated with the onset of tearing and critical conditions, respectively. Using a linear

elastic fracture mechanics analysis, these two structural conditions can be formulated

\ (2.6)

using the stress-intensity factor information given in Table 2.3, i.e., Equation SIF.l.

As requested by industry engineers, available test information (a0, 2a0, cc, 2ac) were

reported in the plane stress and transitional fracture toughness tables along with a

calculation of the critical fracture toughness level based on Equation 2.6. While

stress and crack length information were sometimes available for a calculation of the

onset fracture toughness (Equation 2.5), insufficient space in the table precluded

reporting this toughness.

Plane stress and transitional fracture behavior absorb much more

energy than plane-strain behavior due to the lack of thickness constraint on crack tip

plasticity, and the assumptions of linear elastic fracture mechanics are violated. The

in-plane geometric constraint on crack tip plasticity is required to ensure that gross

plasticity is not the controlling mechanisms of fracture. Extensive study has

indicated that the condition for CCP specimen instability for ductile materials is

given by a net section stress criteria and not by a fracture (crack) controlled

instability criteria. While the fracture toughness values for all plane strain type tests

are reported, those values calculated for stress conditions where the net section stress

(anet = Load/B(W-2ac)) exceeds 80 percent of the tensile yield strength are marked

with an asterisk. Values so marked are not utilized in any mean or standard

deviation calculations summarizing plane-stress fracture critical properties.

2-25


2.3 THE APPARENT FRACTURE TOUGHNESS

The apparent fracture toughness (KApp) is a plane stress and transitional

fracture toughness property that is sometimes utilized as a lower bound on the

critical fracture toughness. Its initial purpose was to preclude measurements of the

tearing process observed during fracture tests of CCP specimens. As noted in Figures

2.16 and 2.17, the initial crack length (2a0) extends during the loading to the critical

crack length (2ac). The two simplest measurements to make in such a fracture test

are those of the initial crack length (2a0) and critical (maximum) stress at failure (ac).

Thus, for simplicity, a KApp fracture toughness calculation was made using

KApp = ac V™7

\ iza0 sec W

(2.7)

Equation 2.7 represents the stress-intensity factor corresponding to the stress and

crack length condition at point "A" in Figure 2.16. It can be noted by comparing

Equations 2.6 and 2.7 that KApp will always be less than or equal to K,. since a0 < ac.

Also, KApp will always be greater than or equal to KoNSET since a0 < ac. A comparison

of the apparent fracture toughness with the onset and critical fracture toughness is

shown in Figure 2.18 for a wide CCP specimen. When the net section stress (anet =

Load/B(W-2a0)) exceeds 80 percent of the tensile yield strength, the KApp values are

marked with an asterisk. Values so marked are not utilized in any mean or standard

deviation calculations summarizing plane-stress apparent fracture toughness

properties.

2.4 R-CURVE (KR VERSUS Aaeff)

The resistance curve (or R-curve) provides a complete description of the tearing

fracture behavior illustrated in Figure 2.16. R-curves characterize the resistance to

fracture of materials during incremental slow-stable crack extension and result from

growth of the plastic zone as the crack extends. ASTM formalized the collection and

reporting of such curves through ASTM Standard E561, covering the standard

practice for R-Curve Determination. As stated by ASTM E561, R-curves provide "a

record of the toughness development as a crack is driven stably under increasing

applied K. They are dependent upon thickness, temperature, and strain rate."

The value of KR (toughness) is calculated using standard stress-intensity factor

equations evaluated with the instantaneous values of applied stress (a) and crack

length (a), as the crack extends. To account for the effects of plasticity, the measured

crack length is enhanced with a plastic zone correction, and an effective crack length

(aeff) is actually used in the calculation of KR. For example, when a CCP specimen is

used to collect tearing resistance data, the KR is calculated based on the standard

stress-intensity factor equation (SIF.l) given in Table 2.3.

KR = a ptaeff Sec^L W

V 2 (2.8)

where c and aeff are the current stress and effective crack length measurements in

the test. The effective crack length for optical measurements is calculated from

where a is the optically measured crack length and ry , calculated as

(2.10)

is the plastic zone size for the current applied stress and crack length. If the crack

length is automatically monitored by compliance techniques, then the effective crack

length is automatically obtained using the two compliance equations presented in

ASTM E561.

2-28


The KR value calculated from Equation 2.8 can be described as a function of the

increment of physical crack extension (Aa = a - a0, a0 = initial crack length) or as

suggested by ASTM 561 as a function of the increment of effective crack length

(Aaeff = (a + r ) - a0). The functions KR versus Aa and KR versus Aaeff are referred to

as R-curves (or resistance curves). Data presented in this Handbook correspond to

the use of the ASTM E561 definition of R-curves, i.e., KR is presented as a function

of AaQ *eff-

All new and existing R-curve data were validated by ensuring that the

remaining specimen ligament in the plane of the crack was predominantly elastic.

For CCP specimens, ASTM Standard E561 requires the net section stress based on

the physical crack size be less than the yield strength of the material, or

For compact tension (CT) specimens, the validity criteria is given by

(2.11)

W-a > — it

max

K°»J

(2.12)

where K^ is calculated using the physical crack size in conjunction with equation

SIF.2 in Table 2.3.

The majority of R-curve data available for the Handbook were obtained using

a compliance based technique for measuring the crack length. The compliance based

technique provides a direct measure of the effective crack length, and therefore does

not require use of Equations 2.9 and 2.10 to estimate the plastic zone size correction.

Therefore, when a compliance based measurement technique is used, only the

effective crack length, effective KR, and Aaeff are reported. As a result, the validity

criteria given by Equations 2.11 and 2.12 were checked using the effective crack

length for those data obtained by a compliance based technique. In some instances,

2-29

this resulted in the last few data points of a particular data set to not meet the

criteria given by Equation 2.12. However, previous experience has shown that the

effect of using Aaeff in Equation 2.12 may be such that the test in question may

appear to be invalid, when in reality it is not. Based on this and the fact that the

tests in question were completed in accordance with ASTM Standard E561, these R-

curves, identified by an asterisk, are included in the Handbook.

One of the fundamental hypotheses behind the application of R-curves to the

prediction of tearing type fractures in thin structures and in structures fabricated

from ductile materials is that the R-curve (material tearing resistance) is independent

of crack length for a given geometry and is independent of geometry and external

loading. As long as the structure matches the monotonically increasing stress-

intensity factor conditions given by the R-curve, the structure will exhibit the same

tearing resistance experienced in the laboratory test specimen. The Damage Tolerant

Guidelines Handbook (AFWAL-TR-82-3073) describes how the R-curve can be applied

to the calculation of critical stress levels in structures.

2.5 FATIGUE CRACK GROWTH RATE

2.5.1 Fatigue Crack Growth Behavior

Under some loading conditions or environmental conditions, cracks can

grow at load levels well below that required to cause fracture. As the crack continues

to grow, conditions become more favorable for fracture, and eventually under the

applied loading fracture does occur. This process whereby cracks are observed to

grow at subcritical load levels is referred to as subcritical crack growth. Illustrated

in Figure 2.19 is a fatigue crack growth curve, which shows the type of behavior

typically observed during a specific subcritical crack growth process; in this case,

damage is done to the material by cyclic (or fatigue ) loading. This section addresses

properties used to measure fatigue crack growth behavior and Sections 2.6 and 2.7

address properties used to characterize sustained load cracking in an environment.

2-31


The objective of fatigue crack growth testing is to determine the rates

at which subcritical flaws propagate under cyclic loadings prior to reaching a size

critical for fracture. These rates are determined from measurements of the crack

extension occurring over an increment of cyclic loading. Typically, these

measurements are made by monitoring crack extension optically on the specimen

surface during the test. From the basic crack length and cycle count data, the

fatigue-crack growth rate is determined as the quotient of the incremental crack

growth divided by the incremental cycle count, i.e., Aa/AN or da/dN, the slope of the

crack growth (life) curve.

The crack growth rate measures the resistance of the material to the

applied loading conditions. The similitude parameter that allows data to be

transferred from one cracked geometry to another is the range in stress-intensity

factor (AK). The AK parameter is the difference between the maximum and minimum

stress-intensity factors (K^ and K^, respectively) for a cycle of loading. The

property of fatigue crack growth rate is described throughout this Handbook as a

function of AK.

2.5.2 Data Acceptance Criteria

In general, similar specimen configurations are used for fatigue-crack-

growth testing as are used for other types of damage tolerant tests. The applied

loads are reduced in magnitude and are cyclic in nature for studies of crack extension

under fatigue loading conditions, and the experimental methods are extensions of the

fracture testing procedures previously described. Instead of applying either a rising

or sustained load to fracture the specimen, a constant amplitude cyclic load is applied

to initiate and grow the crack over a significant portion of the specimen width.

ASTM has published a standard testing method, i.e., ASTM E647, which covers the

collection and reporting of fatigue crack growth rate data. Most of fatigue crack

growth rate data reported in the Handbook were collected and reduced utilizing the

guidelines and methods described by ASTM E647. For CCP and CT specimen

2-32


geometries, the ASTM Standard describes 11 explicit criteria for validating the data;

these criteria are summarized in Table 2.4. A field is included in the handbook

database which notes the da/dN data that failed to meet these ASTM criteria.

2.5.3 Data Reduction Procedures

Data reduction of crack growth rate from the crack length versus cycle

count data was by one of two methods. The secant method was chosen when there

were seven or less crack length versus cycle count measurements. A five point

polynomial movable strip method was used for data with more than seven crack

length versus cycle count measurements. This procedure was similar to the seven

point method recommended in the ASTM standard; the five point method was chosen

to provide additional data points at the extremes of growth rate range.

It is important to note that the calculation of stress-intensity factor

range (AK) is the difference between the maximum and minimum stress-intensity

factors (K^ and K,^, respectively) as defined in ASTM Standard E647. These

calculations are best expressed using equations specific to a given geometry; for

illustration purposes, assume that the test specimen geometry is CCP. Then, the

maximum and minimum stress-intensity factors are given by

K = G sin a * max "max » '

and

K = G \1tCL "nun "mm '

sec — (2.13)

'sec™)* (2-14) W v )

where amax and a^ are the maximum and minimum stresses in the applied loading

cycle. The range of stress-intensity factor is defined as

AK = K^ - K^ (2.15)

By ASTM convention, if K^ is compressive (negative), then K^ = 0, and AK = K^.

2.5.4 Data Reporting Procedures

The presentation of fatigue-crack-propagation rate data is far more

complex than the presentation of fracture toughness data (either KIc or K,.) due to the

large quantities of data which must be treated. Where a fracture test generally

yields a single characteristic toughness value, a fatigue-crack-growth test specimen

generally yields from 10 to 100 rate data points, da/dN, which must be evaluated in

terms of the stress-intensity factor range, AK.

The Damage Tolerant Design Data Handbook presents fatigue crack

growth rate (da/dN) data in both graphical and tabular formats. Subsection 1.6.1

fully describes the presentation format of these data. A graphical format is used to

present da/dN versus AK data and the mean trend of these data are given in tabular

form. The least squares cubic spline approximation method has been selected from

those available to provide a practical method for generating tables with fixed AK

values. A least squares cubic spline approximation is an analytic method of fitting

a "French" curve to a data set. The curve is constructed by fitting different cubic

polynomials on non-overlapping, connecting subintervals over the range of the

independent variable. In the Handbook, the independent variable will be AK. The

boundary points of the intervals are referred to as knots and the cubic polynomials

meet at the knots. The polynomials are also constrained so that the first and second

derivatives are continuous at the knots. The result of this process is a smooth curve

which passes through the center of the data.

Figure 2.20 is an example of a spline curve fit to a da/dN data set

reported by Hudak et al. for 2219-T851 Aluminum alloy. The stress ratio used to

establish the data shown was 0.3. The knots are marked in the figure by the large

dots.

In general, da/dN data are well enough behaved so that a maximum

of five knots was sufficient in generating the handbook tables. The actual number

2-36


of knots used in fitting a curve to a set of data is a function of the root mean square

percent error of the fit to the data and the pattern of the fitted line in da/dN-AK

space.

The mean trend table for a set of da/dN data is generated by selecting

points from the spline curve that has been fit to the data. The AK values will be

chosen such that they are approximately equally spaced in a logarithmic scale and

cover the complete range of AK values expected. The da/dN values are obtained

through the interpolation of the spline curve at the preselected AK values. The

complete set of AK values have been given previously in Table 1.11. Because the

da/dN data do not always span the complete AK range, the table also reports the

minimum and maximum da/dN values corresponding to the recorded minimum and

maximum AK values. The extreme pairs of (AK, da/dN) points correspond to the

extremes of the spline curve.

The root mean square percent error (RMSPE) is utilized to describe the

statistical accuracy for the spline curve fit at each value of the varying parameter.

The RMSPE is given by:

RMSPE = 100 x ^E ( ^ (2.16)

V "" J

where

yf = observed da/dNl; at AKj

Si = da/dN interpolated from table at AKj.

The RMSPE is a measure of how close the data lie to the mean trend

table and has a similar interpretation to the coefficient of variation, i.e., the smaller

the better. The coefficient of variation is used when all the data have the same mean

and is calculated by dividing the standard deviation by the mean and multiplying by

100. For da/dN data, the mean da/dN is a function of AK so this is taken into account

2-37


when calculating the RMSPE. The RMSPE is an average percent error of the

observed da/dN values from the curve established by the mean trend table.

When evaluating the mean trend da/dN description, engineers have

come to rely on an evaluation of the ability of the mean trend curve to repredict the

initial a versus N data and, in particular, to rely on life prediction ratio (Np/NA) which

relates the predicted number of cycles (Np) required to propagate a crack through a

specified increment to the actual number of cycles (NA) observed to propagate a crack

through the same increment. Life prediction ratios between 0.8 and 1.25 are

considered good and a life prediction ratio of 1.0 is ideal.

As a second measure of how well the mean trend curve fits the data,

a summary of the life prediction ratios for the specimens used to generate the mean

trend curve is included at the bottom of Figure 1.12. This summary places the plot

symbol assigned to a specimen test along the LPRS scale at its calculated location.

The actual LPRS value is greater than 2 for tests whose plot symbols are placed

beyond 2 in the LPRS scale.

The life prediction ratios summarized in Figure 1.12 are self

predictions and as such will tend to be good. However, the summary is only valid for

the data used to generate it and therefore should not be generalized to other

situations. The life prediction ratio summary is not intended to predict how well the

mean trend curve will predict crack growth for an arbitrary specimen; however, it

does illustrate how well the mean trend in FCGR correlates with the lives of the

cracks that were used in generating the mean trend.

2.6 SUSTAINED-LOAD CRACK GROWTH RATES

2.6.1 Sustained-Load Crack Growth Rate Behavior

Sustained-load crack growth rate behavior is another type of subcritical

crack growth behavior exhibited by materials which are sensitive to environmental

2-38


attack. This type of subcritical crack growth behavior normally exhibits itself as a

time-dependent crack growth rate process, whereby cracks are noted to extend under

steady-state (sustained) static loading conditions in the presence of environments.

Crack growth mechanisms controlling the sustained-load crack growth rate process

include: stress-corrosion cracking, hydrogen embrittlement, liquid metal

embrittlement, grain boundary separation, and creep. In practice, the time-

dependent cracking process has been found to be driven by internal (residual) tensile

stresses in the fabricated structure, even in the absence of externally applied loads;

typically, however, the stressing condition which drives the crack is provided by

external loads.

The objective of sustained-load crack growth testing is to determine the

rates at which cracks propagate in precracked specimens subjected to statically

applied loads and prescribed environmental conditions. As with fatigue crack growth

rate tests, most of the crack length measurements are made optically on the specimen

surface during the test. Nonoptical methods used to establish cracking include

compliance and stress wave analysis techniques. From the basic crack length and

time data, the sustained-load crack growth rate is determined as the quotient of the

incremental crack growth divided by the incremental time, i.e., Aa/At or da/dt, the

slope of the crack growth (time to failure) curve.

The crack growth rate measures the resistance of the material to the

applied loading for the specified environment. In this case, the similitude parameter

that allows data to be transferred from one cracked geometry to another is the static

stress-intensity factor (K^). The K^ parameter is the stress-intensity factor

evaluated for the applied loading and current crack length. The property of

sustained-load crack growth rate (da/dt) is described throughout this Handbook as

a function of K,^.

2-39


2.6.2 Data Acceptance Criteria

For the most part, the testing methodology for da/dt properties follows

that utilized to obtain da/dN properties. There are, however, no current ASTM

standards that specifically cover the collection of da/dt data. Sustained-load data

have been obtained with a variety of specimens including double cantilever beams

(DCB), tapered double cantilever beams (TDCB), compact tension (CT) specimens,

cantilever beams (CANT), single-edge-notch tensile (SENT) specimens, part-through-

surface crack (PTSC) specimens, and center-cracked panel (CCP) specimens.

One validity criterion that is sometimes applied to da/dt data is that

the thickness dimension and crack length must be greater than 2.5 (KIc/ays)2. No

da/dt data were excluded from the 1993 revision, however, based on this criteria due

to the scarcity of da/dt data. The reader will find KIc, ays and thickness reported with

da/dt data whenever these were available.

Readers should note that sustained load crack growth rate data in

aluminum alloys in planes other than those parallel to the surface of rolled plates are

questionable because of the localized corrosion that occurs on the planes even though

the initial notch and crack orientation are normal to these planes.

2.6.3 Data Reduction Procedures

Data reduction of sustained-load crack growth rates was accomplished

using the secant method applied to crack length (a) measurements recorded as a

function of time (t). These calculations and those of static stress-intensity factor were

provided to the data processing organization for reformatting.

2.6.4 Data Reporting Procedures

The data reporting procedures for sustained-load cracking data are

similar to those discussed in Subsection 2.5.4 for fatigue crack growth rates. The

2-40


major difference between the two subcritical cracking rate reporting procedures is

that da/dt vs K^ describes the sustained-load behavior whereas da/dN vs AK

describes the fatigue behavior. The reader might also note that no a vs t were

available to compare with the integrated crack growth mean trend data and therefore

no life prediction ratios were presented.

2.7 THRESHOLD STRESS INTENSITY (Klscc)

2.7.1 The Threshold

In many environments, materials exhibit a condition whereby cracks

are not observed to grow if the static stress intensity factor is below a critical level,

designated KIscc. This property is specific for a given material in a given environment

within a specified time period. In high-strength materials, KIscc may be only a small

fraction of the plane-strain fracture-toughness value (Klc) of the material. In lower

strength tougher materials where plane-strain conditions still prevail, KIscc may

approach or equal KIc, if the environment has little or no effect on the stress intensity

required to propagate a crack.

KIscc data have been obtained with a variety of specimens including:

Cantilever beam (CANT), 3-point loaded bend beam (NB), 4-point loaded bend beam

(4-NB), Single-edge notch tensile (SENT), Center-cracked tensile (CNT), Part-through

surface-crack (PTSC), Compact tension (CT), Bolt loaded WOL (BWOL), Double

cantilever beam (DCB), and Tapered or contoured double cantilever beam (TDCB).

All specimens are notched and precracked by fatigue, and many specimens are side

grooved (SG) to ensure that the crack propagates in one plane perpendicular to the

applied tensile loading and also to minimize the contribution of shear lips at the

edges of the crack.

The types of specimens for determining KIscc fall into two broad

categories: those that are loaded by weights or tensile machines (see Figure 2.21) and

those that are self-loaded as by bolts. The former require bulky setups to

accommodate lever arms, weights, and tensile machines while the latter are compact

and portable. Thus the environment is applied to the externally loaded specimens

usually in the form of a small container sealed onto the specimen, while the self-

loaded specimen may be completely immersed in the environment.

Under dead-weight loading conditions, the usual practice is to run a

number of specimens at various stress intensities less than KIc for a finite length of

time (more than 24 hours and usually about 500 hours) to establish KIscc. Another

method is to step load a single specimen until the crack starts to propagate. This

method requires holding after each load increment for a sufficient time to establish

that crack propagation does not occur.

Under bolt self-loading conditions, sufficient load is first applied to the

bolt to cause the crack to extend beyond its precracked position. The specimen is

then exposed to the environment. As the crack propagates in the environment, the

stress-intensity factor decreases at the tip of the advancing crack until the crack

arrests at KIscc. Specimen length must be sufficient to ensure that the crack arrests

before completely penetrating the specimen, thus assuring that a value is obtained

for KIscc.

2.7.2 Conditions for Validity of Data

There are no ASTM standards that specifically cover the collection of

KIscc data. The criterion typically used to validate K^ data is that the thickness

dimension (B) and initial crack size after precracking (a0) are greater than the ASTM

E399 requirement for plane-strain fracture toughness, i.e., that B and a0 > 2.5

(Kfc/Gyg)2. However, because the initial crack size is not currently stored in the

handbook database, only the thickness requirement was checked. Data which did not

meet this criterion are identified in the KIscc tables with an asterisk. Many tests

reveal a drastic reduction in the stress intensity required to propagate a crack even

2-43


though the 2.5 (Klc/ays)2 criterion is not met. Although these data are not

recommended for material selection and design purposes, they do indicate a

qualitative effect.
