The reliability evaluation system for ceramic gas turbine components was developed. This system ‘GFICES’ is based on the statistical strength theory using 2 parameter Weibull distribution. Main functions of this system are fast fracture analysis, static fatigue analysis, dynamic fatigue analysis and the evaluation of the effect of proof testing. In addition, several other functions such as application of bimodal Weibull theory and consideration of aging degradation of ceramic components are available. Being applied to the first stage ceramic bucket, this system has been found to be effective for the strength evaluation of ceramic structural components.
