Abstract
Using a modified thermal-shock model, a method for theoretical evaluation of the actual strength of single-phase polycrystalline refractory and ceramic materials has been developed. A formula for strength analysis over a wide temperature range has been derived. The calculated actual strength is a parameter for actual materials and thus can be used for predicting the behavior of materials under loading conditions within the framework of linear elastic fracture mechanics. In the region of Debye temperature, the theoretical strength versus temperature curve for single-phase materials exhibits a “dip” which, however, fails to be resolved experimentally because of the insufficient accuracy and poor reproducibility of measurements.
