Development of a New

Altair-Customized Database

of Advanced Material Properties

Engineering Metals Properties

Requirements

• Challenge - Engineers need precise material

properties information

• Today - Most of CAE packages have

some material libraries, but they are

either empty or populated with only

a handful of most common materials

• Engineers need to search and occasionally find

some data in scattered sources such as

standards, books, articles and the Internet,

some of them being even free

• Results in…

4 Key to Metals - The World’s Most Comprehensive METALS Properties Databases


5) Time wasted on searching for properties

instead of engineering

4) Lost opportunities to optimize design

3) Difficulties in communication with purchasing

and manufacturing, especially internationally

2) Creating islands

of information within

the organization

1) 29.3% of all failures

are caused by poor design

or lack of knowledge about

material properties and

standard specifications!

Example


Yield stress

Aluminum: 240-310 MPa

Stainless steel: 275-350 MPa

Carbon steel: 205-275 MPa

Is it?

• Aluminum (240-310 MPa ???) • Grade 1060, ASTM B 736, Plates, sheets; Annealed (O);

1,295 - 76,2 mm; YS = 17 MPa

• AA 2014, Plates; Solution heat treated and artificially aged (T62); 12,7-25,4 mm; YS = 407 MPa

• Stainless steel (275-350 Mpa ???) • S30403, ASTM A 814; Pipes; Heat treated; YS = 170 MPa

• Type 630, ASTM A 693, Plates, sheets, strips; Precipitation hardened (PH496); YS = 1070 MPa

• Carbon steel (205-275 MPa ???) • A 1008 EDDS, ASTM A 1008; Sheets; Cold rolled; YS = 105 MPa

• 42 NCD 16-M , AFNOR NF A 32-058, Castings; Quenched and tempered (Class 1); YS = 1500 MPa

• Dependency on the heat treatment • S21400, ASTM A 580; Wires; Annealed; YS = 345

• S21400, ASTM A 580; Wires; Cold drawn; YS = 1310

• The ratio is ~3,8:1 !

Use Case 1: Linear Data

• Need - Material data needed

for calculations in the elastic range

• Today’s Method - Some data

CAN be found for some materials

from diversified data sources,

some of them being even free

• Issues with Today’s Method

• Solution - KEY to METALS Standard set

– Information for over 200.000 materials worldwide

through readily available standard dataset

– Information available in seconds

– High quality of the data due to certified process

and strong data coupling with standard

specifications

Use Case 2: Advance Data


• Need - Material data for advanced CAE calculations • Stress-strain curves for calculations in the plastic

range, fatigue properties, fracture mechanics parameters, etc…

• Challenge - Data is very difficult to find at all • Best case scenario: several hours searching for data

• Often, the time span for searching can be in weeks, resulting in costly delays

• Frequently, the data is not found at all

• Even more possibilities for dangerous errors

The Solution:

KEY to METALS

Extended Range

www.keytometals.com

Extended Range Data Scope

• The number of materials with the properties directly available online (April 2013): 1) Stress-strain curves: >3000 materials (~35,000 curves) 2) Formability curves: >1500 materials 3) Fatigue: >3800 materials (~20,000 datasets) 4) Fracture mechanics: >500 materials 5) Creep data: >6000 materials

• These numbers are already considerably larger than any other collection in the world

• The numbers and functionalities are continuously increased through monthly updates & upgrades
