Effect of Toughening Mechanisms of Crack Bridging on Ceramic Materials

Article Preview

Abstract:

A toughening model of crack bridging reinforced ceramic matrix composites is presented. It was shown that this transition closely relates to the extent of toughness, particle size or volume fraction, and the particle yield stress. The constitutive equation is obtained through micromechanical considerations based on crack bridging toughening. The results show that the model is in good agreement with SEM results.
