Abstract:The synergistic effects of loading sequence and interface wear on the damage evolution in fiber-reinforced ceramic-matrix composites (CMCs) have been investigated. The shear-lag model combined with matrix cracking model, interface debonding criterion and interface wear model has been adopted to analyze the damage evolution in CMCs under different loading sequences. The relationships between damage parameters, i.e., the fatigue hysteresis loops, fatigue hysteresis dissipated energy, and matrix crack spacing, interface debonding and sliding, have been established. The effects of stress levels, matrix crack spacing, fiber volume fraction on the damage evolution of CMCs have been analysed. The fatigue hysteresis loops, fatigue hysteresis dissipated energy, and the interface slip lengths of cross-ply SiC/CAS composite have been predicted. © 2017 International Committee on Composite Materials.
