Theoretical Meso-model of Al_2O_3/ZrO_2 Ceramic Response Under Compression

摘要

This paper presents theoretical modeling of two-phase ceramic composites subjected to compression. The meso-mechanical model allows for inclusion of all microdefects in the polycrystalline structure that exists at the grain boundary interfaces and inside the grains. The constitutive relations for the Al_2O_3/ZrO_2 composite with the gradual degradation of the material properties due to different defects development were formulated.
