Application of the equivalent material concept to fracture of U-notched solids under small scale yielding

Procedia Structural Integrity, 2018
Abstract This paper studies the applicability of the equivalent material concept developed by the author to the fracture of elastoplastic material due to the presence of U-notches. The approach of equivalent material concept consists of simplifying the study of an elastoplastic material reducing it to the linear elastic case with a maximum stress ...
