ON THE RESIDUAL TENSILE STRENGTH OF CRACKED STRUCTURAL ELEMENTS
NEW YORK UNIV N Y SCHOOL OF ENGINEERING AND SCIENCE
Pagination or Media Count:
A modified stress concentration factor approach is presented for determining the residual strength of structural elements containing cracks of limited extent. The ductility ratio which characterizes the material in the presence of a stress concentration and the effective radius of the crack are evaluated as a single material parameter from the test data correlation scheme presented herein. Test data for Al alloys and steel were analyzed. Author
