Abstract
A stress-strength interference theory is formulated to treat ceramic component fracture caused by volume embedded cracks. Spatial stress fields obtained from finite element calculations are transformed to obtain equivalent stress probability distribution functions for both normal stress and shear sensitive fracture criteria. These are combined with Weibull and Poisson distributions, respectively, for the strength of the solid containing a single crack and the crack densities to obtain fast fracture probability estimates. The effects of geometry and fracture criteria are examined for components with equal volume and maximum stress.
