The Micromechanical Stress Field of Cermets Composite Containing Interfacial Arc-Microcracks
The emerging cause of arc-microcracks is interpreted and the interaction between ceramic particles and arc-microcracks is accounted for determining the average disturbance strain and equivalent eigen strains by using Mori-Tanaka method. Then the micromechanical stress field of the cermets is estimated. Results show that the micromechanical stress field is not associated with the distribution of arc-microcracks. The stress in matrix and ceramic particles will increase when the volume fractions of arc-microcracks increases.
