When ceramic matrix composites are subjected to fatigue loading levels sufficient to initiate microstructural damage to the constituents, the mechanical response of the laminate, e.g. the residual strength, stiffness and life of the composite, is gov

This study proposes a methodology for modeling the fatigue response of cross-ply ceramic matrix composites (CMCs). The micromechanics based analysis and failure criteria are formulated to model stress-strain hysteresis, strain ratchetting and S-N beh

A three-dimensional micromechanics formulation for fiber-reinforced composites containing viscoplastic matrix materials is presented. The micromechanics model is based on the relaxation of the coupling effect between the normal and shear stresses. Th
