The interface failure observed in quasi-static fiber pushout tests performed on a model fiber-reinforced composite is simulated using a cohesive volumetric finite element scheme. The numerical analysis is conducted under axisymmetric condition. The debonding process is captured with the aid of intrinsic rate-independent cohesive elements. The augmented Lagrangian approach is used to solve the frictional contact between the crack faces. The numerical method is first applied to a model polyester/epoxy system, showing excellent agreement with the experimentally obtained load-deflection curve and with the observed evolution of the debonding length. The numerical scheme is then further applied in a parametric study of the effects of the friction coefficient, the interfacial bond strength and the process-induced residual stresses on the fiber-matrix interface failure process.
