Modelling of dynamic damage and failure in aluminium alloys [PDF]
, 2012 A physically based damage and failure model, applicable to orthotropic metals is proposed in this paper. To account for the physical mechanisms of failure, the concept of thermally activated damage initially proposed by Klepaczko [1], has been adopted as

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
