摘要

In ceramics, it is important to examine the mechanical properties such as the static strength, the fatigue, and the anelastic relaxation. Generally, the static strength is measured through three or four-point bend test, and the fatigue properties are obtained from the bend test or the rotating bending test. In these tests, because the stress gradient is formed in the specimen, the precise stress-strain response cannot be obtained and the strength is sensitive to the condition of the surface finish. Furthermore, these methods are not suitable for evaluating the relationship between the mechanical properties and the microstructure, because the accurate stress condition at the observed area is difficult to identify. For examining the anelastic properties, the internal friction is generally measured by applying the flexural resonance method or a free-decay procedure using an inverted torsion pendulum. However, the frequency dependence of the internal friction is impossible to measure using these methods. Thus, the internal friction is usually measured as a function of the temperature.
