Abstract
The condition for progressive debonding with friction along the debonded interface is considered for the bridging fiber in the crack-wake of fiber-reinforced ceramic composites. The energy-based criterion is adopted in the present study to analyze the debond length, the crack-opening displacement, and the displacement of the composite due to interfacial debonding. The results are identical to the previous results obtained from a simple approach, in which interfacial debonding is assumed to occur when the mismatch in the axial strain between the fiber and the matrix reaches a critical value. Furthermore, the mismatch-strain criterion is found to bear the same physical meaning as the strength-based criterion.
