OS08W0290 The fracture model of porous ceramics subjected to mechanical load

Abstract

The fracture tests of porous ceramics were carried out under tensile and bending conditions, and a formula model of fracture process was investigated in order to clarify the fracture properties. As the formula model, the assemblies of pore-element and matrix-element were proposed, and the experimental results were estimated using an inverse analysis method. As the results, the stress-strain behaviors of porous ceramics under tensile load were successfully simulated using our devisal formula model.
