Stiffness of Cermets Containing Interfacial Arc-Microcracks

摘要：

The interfacial arc-microcracks have large influence on the behaviors of cermets. The emerging cause of arc-microcracks is interpreted and the interaction between ceramic particles and arc-microcracks is accounted for determining the equivalent eigen strains by using Mori-Tanaka method. Then the effective volumetric modulus and shear modulus of the cermets is estimated. The results show the effective volumetric modulus and shear modulus of the cermets is associated with the stiffness of the matrix and ceramic particles, the volume fractions of ceramic particles and arc-microcracks, the subtending angle and thickness of arc-microcrack.
