Thermally Induced Fracture
This chapter outlines both the physics and the testing procedures that can be used to determine the susceptibility of ceramics to thermal stress‐induced failure. Thermally induced fractures can be identified by their fracture pattern. Thermal stress fractures in a part produce wavy cracks. The general approach to measuring thermal shock resistance in ceramics has been to quench flexural specimens from some elevated temperature into an ambient temperature bath, usually water. There are two conditions that should be considered in conducting quench tests, the first in which the Biot number is quite large and the other in which it is low. Because of the difficulty in predicting thermal stress resistance, it becomes necessary to perform tests on the particular material to determine its susceptibility to thermal shock. One should be aware that these tests provide only a relative guidance to the use of the material in different conditions.
