The material system of interest in this article is the whisker-toughened ceramic matrix composite. Analysis of components fabricated from this material requires a departure from the design philosophy (i.e., the factor of safety approach) prevalent in designing metallic structural components, which are more tolerant f flaws. Since failure of components fabricated from this material is governed by the scatter in strength, statistical design approaches must be used. A public domain computer algorithm has been developed that, when coupled with a general-purpose finite-element program, predicts the fast-fracture reliability of a structural component under multiaxial loading conditions. The present version of this algorithm has been given the acronym TCARES (Toughened Ceramics Analysis and Reliability Evaluation of Structures).
