Effect of pore morphology on elastic, heat conduction and thermal shock fracture behaviors of porous ceramics

In this study, four different porous microstructures were modelled and simulated using a random algorithm and a three-dimensional finite element method. The effect of pore morphology on the elastic modulus and thermal conductivity of the porous ceramic was investigated, and their possible roles in determination of thermal shock induced stress were studied using the results of finite element simulations. Finally, the relationships between the porous microstructure and their thermal shock cracking resistance were discussed, in terms of pore shape and pore morphology.
