Abstract

![CDATA[The influence factors of thermal shock resistance of porous ceramic materials are analysed from the point of stress criterion and energy criterion. Results show that material properties, relative density and initial crack have important effects to thermal shock fracture of porous ceramic materials. In energy criterion, the total elastic energy is given. The driving force for crack propagation is provided by the elastic energy stored at fracture. When the elastic energy stored in porous ceramic materials is larger than the fracture energy, the crack will propagate. The relationship between crack length and initial crack length is given. In addition, the reason why the thermal shock resistance of porous ceramic materials is larger than dense ceramics is explained.]]
