A Reliability Evaluation System for Ceramic Gas Turbines : Solid-Mechanics, Strength of Materials

概要

論文の詳細を見る
A reliability evaluation system for ceramic gas turbines was developed. This system combined the results of a finite element stress analysis with a probabilistic analysis of ceramic structures. In this system, a new probabilistic method was used to estimate time and cycles to failure of multiaxially stressed ceramic structures. Using this system, fast fracture, static fatigue and dynamic fatigue can be evaluated. Also, the effect of the proof test on these failure modes can be evaluated quantitatively.
