Abstract

A three-component model of copper-based composite loaded by tensile forces is proposed. The effect of a nonhydrostatic stress state and the formation of microplastic zones cause the transition of the composite from an isotropic to an anisotropic state. We calculate the tensor of effective elastoplastic modulii of the model as a function of the applied load and of the microplastic zone concentration.
