摘要

Two approaches to modeling the cyclic damage-plasticity behavior of metal matrix composites are presented in this paper, namely: a micro (micromechanical-damage) and a macro (continuum-damage) based approach. Each of these approaches involves a fictitious undamaged 'effective' configuration to which the plasticity equations are applied and constitutive queations derived. Using the equations for the transformation of stress from the undamaged to the damaged configuration, the transformation of these equations to the actual damaged configuration is performed.
