摘      要：The temperature field of two types of porous graded ZrO2 subjected to thermal shock loading is analyzed in this paper using the finite‐element method. The numerical simulation results indicate that the structure of ZrO2 with an un‐symmetric porous microstructure is superior to symmetric one and that, ignoring the influence of temperature dependent properties, the effects of thermo‐mechanical coupling can be ignored if the imposed heat flux density is less than 4 WM/m2.
