Non-Destructive Failure Prediction for Brittle Solids

摘要

Structural design with brittle materials requires that the stress level in the component correspond to a material survival probability that exceeds the minimum survival probability permitted in that application. This can be achieved by developing failure models that fully account for the probability of fracture from defects within the material (including considerations of fracture statistics, fracture mechanics and stress analysis), coupled with nondestructive techniques that determine the size of the large extreme of critical defects. Approaches for obtaining the requisite information are described in this paper. (ERA citation 06:009522)
