Porous ceramics are applied to filter materials in various fields such as hot temperature energy apparatus and purifier. But their strength properties are not clarified enough to make a strength design. The strength properties of porous ceramics are influenced by the pore density and matrix ceramics. Therefore, a formula model for mechanical damage with the increase of tensile load was devised in order to clarify their influence. The stress-strain behaviors of porous ceramics under tensile load were successfully simulated using our devisal formula model. The influences of pore density and matrix ceramic strength properties on maximum strength, undamaged strength, bulk elastic modulus and so were found from stress-strain behavior obtained by the simulation.
