Abstract
In this paper, the effect of preexisting defects on strength of eutectic composite ceramic mainly composed of rod-Shaped crystals is considered. In line with the microstructure characteristic of eutectic composite ceramic, its micromechanical model is set up. Defects are assumed to be lamellar, and matrix around is transversely isotropic. Then, the damage stress field is obtained by Chaboche’s damage theory. Finally, the micromechanical strength of eutectic ceramic composite is predicted, and its influencing factor is analyzed.
