Abstract

Abstract: A coupled micro–meso-scale modeling strategy is proposed to investigate the damage mechanism of 2D SiC/SiC ceramic matrix composites. The multi-scale modeling begins with microstructure construction using the representative volume elements (RVE). The effective properties of the SiC/SiC yarn are computed using the micro-scale RVE model. At meso-scale, the Tsai-Wu and Mohr's failure criteria are used to describe the different failure modes of yarn and matrix. A satisfied agreement with experimental results obtained by uniaxial tension tests validates the proposed multi-scale modeling strategy. The damage behavior of 2D SiC/SiC composites under in-plane shear loading is further investigated.
