  • Amulti-scale constitute model for ceramic matrix composite(CMCs) was presented in this paper by using high-fidelity generalized method of cell(HFGMC).Based on the microstructure and damage characteristics of CMCs,a representation volume element(RVE) and damage variables were defined.Then,the evolution of damage variables was calculated by HFGMCmodel to obtain the relationship between global stress and global strain.The numerical example shows that the result predicted by the model is consistent with the experimental result,and the model could simulate the global performance and the damage evolvement of CMCs exactly,thus providing an effective method for the micro-macro analysis of CMCs.
