N2 - Asymmetric thermal shock resistance of porous ceramic materials has been studied. The plate, initially at uniform temperature, is exposed to a sudden temperature on its one surface whilst thermal insulation are considered for the opposing face. The temperature field and transient thermal stress field in the porous ceramic plate uncracking are calculated. Then, the weight function method is used to obtain thermal stress intensity factor at crack tip. The effects of relative density and thermal shock temperature on the crack propagation of the porous ceramic plate are analyzed. Finally, the thermal shock resistance of the porous ceramic materials is acquired based on stress criterion and fracture toughness criterion.
