Abstract

This study employs Peridynamic (PD) theory to predict crack deflection in axisymmetric ceramic matrix composites (CMC). It specifically employs the weak form of PD equations of motion which enables the direct imposition of natural and essential boundary conditions. The results indicate that the critical stress ratio between the coating and matrix have a strong influence on crack deflection in a CMC. Also, it was observed that the smaller this ratio is, the earlier the crack deflection in the fiber coating occurs.
