In this study, based on the linear fracture mechanics, we proposed the Finite Element Analysis method to consider with stochastic uneven sintering effects on strength of ceramic matric composite. Using proposed method, we can examine the fracture behavior depending on the sintering effects which corresponds to the relative density, the initial defect (pore size), and the grain size. In addition, it is shown that the Weibull distribution of 3-point or 4-point bending tests can be analyzed within the framework of FEA.
