DEVELOPMENT OF PLANE STRAIN FRACTURE TOUGHNESS FOR HANDBOOK PRESENTATION.
TRW EQUIPMENT GROUP CLEVELAND OH MATERIALS RESEARCH AND DEVELOPMENT DEPT
The purpose of this program is to experimentally determine plane strain fracture toughness KIC values for a variety of high strength-to-weight materials over a range of test temperatures. The ultimate objective is to develop the data in a form which would be useful for presentation in handbook form. During the current report period fracture toughness data were generated for 4140, 17-7PH, PH15-7Mo, and 17-4PH steels over test temperatures between -100 and 75 F. Author
