Experimental research was performed to study the anisotropic elastoplastic responses of SiCp/Al composite sheets. To investigate the effects of the composite processing, two sets of specimens cut from the heat-treated and as-rolled composite sheets are tested using a universal material-testing machine. The dependence of the strength, plastic flow, and strain ratios on the rolling angles are discussed in detail. To model the phenomena observed in the experiments, a micromechanics based damage framework is developed. The interfacial debonding and the rolling angle’s effects are integrated into this model. Good consistence between the experimental results and the analytical predications shows the validity of the theoretical model.
