Damage evolution of random particulate composites is formulated by combined micromechanics and damage mechanics. Damage mechanics is applied to filler particles to describe interfacial debonding, which in turn incorporated into Mori-Tanaka's mean field theory for stiffness prediction of damaged composites. The model uses an energy balance concept to account for nonlinear behavior due to particle debonding. With this model, the effect of partial debonding on anisotropic damage development of composites are analytically investigated.
