✦ Synopsis

Abstract

Dynamic crack propagation routes in composites were investigated using numerical methods. The interfacial strength was characterized by means of the interfacial nodal constrained failure. Five different micro‐damage modes around a broken fiber and the corresponding stress/strain curves were obtained with the interfacial strength increasing. It was proved that the shear stress concentration region appears to be different as the interface varying from weak to strong and that the recovery of fiber load‐supporting with a strong interface is better than that with a weak interface. Experimental work has been done and the available results agree well with corresponding simulation results.

The influence of matrix degradation on fiber-mode mechanical properties of unidirectional composites is considered. In this case the strength of the composite reduces to the strength of a bundle of fibers. The longitudinal Young's modulus is evaluated as a nonlinear function of applied stress. In th
