Ductile Fracture and Failure Criteria of Structural Steels

Abstract

Progress is reviewed for a program which examines aspects of ductile fracture of structural steels. The research seeks to establish multiaxial failure criteria which have sufficient microstructural sensitivity to account for variations in microstructure such that fracture initiation can be predicted. The research involves both experimental and computational analysis. Progress for the period March 1, to May 31, 1994 is reviewed for (1) the initiation of a study of failure criteria of structural steels and (2) the conclusions of a two-dimensional modeling study of void linking during ductile, microvoid fracture.
