Abstract

In this paper, a novel material model for anisotropic metals is proposed. Fracture prediction using the proposed model is based on stress-rate dependency related with non-associated flow rule in which an arbitrary order function for both the yield and plastic potential functions are used. In addition, an explicit formulation of the equivalent plastic strain increment that is plastic-work-conjugated with the equivalent stress is also presented. Then, fracture prediction analyses are conducted by using the 3D local bifurcation theory.
