Cohesive Zone-Based Damage Evolution in Periodic Materials

The cohesive zone model (CZM) is then implemented to simulate progressive separation of adjacent phases or subdomains. The new capability is verified in the linear region upon comparison with an exact elasticity solution for an inclusion surrounded by a linear interface of zero thickness in an infinite matrix that obeys the same law as CZM

Effect of Toughening Mechanisms of Crack Bridging on

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.
