    Abstract

    Plates of both square and round geometries are tested to determine the strength and fatigue properties of ceramics under multiaxial stresses. The necessary tolerances required for accurate testing are not well documented in published literature. The stresses in square and round plates subjected to loading between concentric rings were investigated via the finite element analysis method. In particular, the effects of load ring concentricity and the amount of the plate overhanging the support ring were investigated. Also, the errors generated by testing square plates between circular rings were investigated. The analyses were performed in support of an effort by the American Society for Testing and Materials Committee C28 on Advanced Ceramics to standardized multiaxial testing of ceramic plates.
