This edition entirely revamps the 1975 edition. This edition is arranged by alloy*rather than by property as in the previous addition. The data are presented in eiqhtchapters and four volumes. Plane-strain fracture toughness (KIC), critical plane

4 stress fracture toughness, apparent fracture toughness, R-curve, 'fatigue crack* growth rates, sustained-load crack growth rate and threshold stress intensity (KISCC)

data are presented for stainless steels, titanium alloys, nickel-base alloys, alloysteels, 2000-, 6000- and 7000-series aluminum alloys.

ACKNOWLEDGMENT

This document was published by the Metals and Ceramics Information Center (MCIC), Battelle'sColumbus Laboratories, 505 King Avenue, Columbus, Ohio 43201-2693. MCIC's objective is to

provide a comprehensive current resource of technical information on the development and utilizationof advanced metal- or ceramic-base metals.

MCIC is publishing this revised and expanded edition of the Damage Tolerant Design Handbook toincrease the availability of information to the technical community. The loose leaf format was selectedto facilitate updating the handbook as new information becomes available. This edition is a completelyrevised and expanded version of the original handbook first published by MCIC in 1972 and revised in1973 and 1975.

The Center is operated by Battelle-Columbus under Contract Number DLA900-83-C-1744 for the U.S.Defense Logistics Agency; technical aspects of MCIC operations are monitored by the Office of theDeputy Under Secretary of Defense Research and Advanced Technology. The support of thesesponsor organizations is gratefully acknowledged.
