| Abstract: | Based on the conservative law of energy, the establishment of Hasselman's integrated theory of thermal-shock fracture resistance and thermal -shock damage resistance of ceramics and its applications were commented. The predomenant mechanisms of thermal -shock resistance at different stages in the thermal-shock damage process were analysed and explained. The effect of cracks in ceramics on thermal-shock resistance was discussed and the principles and methods to manufacture ceramic materials in which cracks exist were proposed. |
