Size Dependent Stiffness of Composite Ceramic with Partial Debonding Interphase

The partial debonding interphase has large influence on the behaviors of composite ceramic. The emerging cause of partial debonding interphase is interpreted and the interaction between particles and partial debonding interphase is accounted for determining the equivalent eigen strains by using the four phase model method. Then the effective stiffness of composite ceramic is estimated. The results show the effective stiffness is associated with the stiffness of the matrix and particles, the volume fractions of particles and partial debonding interphase, the subtending angle and thickness of partial debonding interphase.
