A micromechanically motivated uncoupled model for ductile fracture prediction
工程科学学报, 2017 This paper is a contribution to the ductile fracture prediction by the proposal of a new uncoupled ductile fracture criterion. In the new criterion, two typical void deformation models were carefully considered, with the plastic strain increment regarded
