Comparison of Plane-Stress Fracture Toughness for Three Aluminum Sheet Alloys.
Abstract
A program for evolving analytical procedures to characterize the fracture resistance of high-strength sheet metals has been initiated. The first phase of this program is concerned with the development of a standard plane-stress test method for reliable characterization of high-strength sheet alloys. The test incorporates fracture mechanics principles to define the relationship between the stress and critical crack size at instability in terms of a single parameter. A center-cracked sheet panel has been selected as the most promising test-specimen configuration to investigate this relationship. (Author)
