Abstract

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 of 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).
