A Simplified Structural Ceramic Design Technique

Abstract

This paper reviews the basic theory of the ceramic design methodology, and discusses the relative importance of the various parameters. A simplified technique is presented for estimation of the component reliability from the component stresses or for determining an acceptable design stress. These techniques can be used with or without a finite element stress analysis. A comparison of predicted probabilities of failure for actual components is made between the traditional computerized Weibull analysis and this simplified technique which shows reasonable agreement. An example of how to use this method is presented and an error analysis is included. This technique can be used to aid in material selections and design modifications, rank alternate designs and help the individual develop a “feel” for successful ceramic design.
