A brief evaluation of the behavior of some important ceramic materials subjected to thermal and acoustic stress is presented. The criteria for evaluation included measurements of transverse rupture strength, elastic modulus, and internal friction. The chief emphasis is on a brief review of pertinent literature and techniques developed for performing such tests. Comments on the principal results of recent investigations are included. The problem of acoustic fatigue in ceramics was clearly demonstrated. This phenomenon may have important ramifications for the potential use of ceramics in acoustically active environments e.g., gas turbine blades, bearings, and seals.
