Micromechanical Elastoplastic Damage Mechanics for Elliptical Fiber-Reinforced Composites with Progressive Partial Fiber Debonding

By considering progressive interfacial partial debonding, a multi-level elastoplastic damage formulation is proposed to predict the overall transverse behavior of continuous elliptical fiber-reinforced metal matrix composites within the framework of micromechanics and homogenization. Based on the method of equivalent inclusion and taking the evolutionary interfacial debonding angle into consideration, partially debonded isotropic elliptical...
