Fracture of ceramics is essentially brittle and a probabilistic phenomenon. Parameters for fracture such as fracture strength, fracture location and fracture time should be treated statictically or stochastically, and scattering and volume effect of fracture strength have been explained by Weibull distribution which is a main statistic distribution1. However, the fracture phenomenon which controls the final strength and fracture is intrinsically cumulative and should be treated stochastically2. An integrated result of microfractures before the final fracture demonstrates the final strength of final toughness. The final strength has been treated statistically, but the probabilistic investigations for microfracture have not been reported.
