• Static fatigue lifetime of structural ceramics under biaxial stress state has been estimated and compared with experimental fatigue data. Biaxial static fatigue test was done by ring-on-ring test method at 1350℃ in the air. Lifetime was predicted on the basis of a Weibull multiaxial distribution function and subcritical crack growth, using the results of stress analyses by the finite element method. Lifetime was calculated as a function of fracture probability, P_f. The predicted lifetime envelope constructed by lines of P_f=1% and 99% covered the scattered experimental fatigue data. This results confirmed that the lifetime prediction conducted in this study is useful for the reliability analysis and assurance technology for designing ceramic components.
