Methodology for Relating the Tensile Constitutive Behavior of Ceramic‐Matrix Composites to Constituent Properties

A methodology for the straightforward and consistent evaluation of the constituent properties of ceramic-matrix composites (CMCs) is summarized, based on analyses from the literature. The results provide a constitutive law capable of simulating the stress/strain behavior of these materials. The approach is illustrated using data for two CMCs: SiC/CAS and SiC/SiC. The constituent properties are also used as input to mechanics procedures that characterize stress redistribution and predict the effect of strain concentrations on macroscopic performance.
