Abstract

Abstract

Based on the nucleation-and-growth model of microvoids and the phenomenological assumption, a microvoid damage evolution equation was acquired. The material constitutive relation considering the effects of damage and temperature softening was developed. The damage evolution and material constitutive equations were embedded into the fininte element software ABAQUS with its material interface to simulate numerically the impact spallations of DA6C and 921 steel plates. The simulated results are in good agreement with the experiments.
