Abstract
The prediction of room temperature fast-fracture failure probability of SiAlON valves, with 95% confidence estimates of those predictions, were made through the combination of censored flexure and tensile strengths of a SiAlON ceramic, their Weibull analyses, and finite element analysis of a prototype diesel exhaust valve, in AlliedSignal's CERAMIC and ERICA life prediction codes. The life prediction algorithm used, the finite element analysis, the dependence of specimen grinding parameters and specimen geometries (and their strengths), and `data pooling' on the resulting predictions of failure probability are discussed. Within 95% confidence, the failure probability predictions correlated quite well with experimental fast-fracture strengths of SiAlON valves for all independent parameters examined.
