摘要: Accurate modeling and efficient analysis of the metal matrix composite materials failure mechanism during high velocity impact conditions is still ultimate goal for many researchers. The objective to develop a micromechanical constitutive model that can effectively simulate damage problem materials. Therefore in this paper, multiscale couples anisotropic with viscoplastic deformation presented here as solution situation. This coupled formulated based on thermodynamic laws. Nonlinear continuum mechanics used heterogeneous media assesses strong coupling between viscoplasticity damage. It includes directional effect fiber evolution back stress development strain material behavior related problems.
