Abstract

Publisher Summary The stress and strain concentration tensors derived in this chapter are for fibrous composites with continuous fibers that undergo damage in both the constituents and the interfacial damage. The damage in the matrix includes the nucleation and growth of voids and micro-fracture while in the fibers include micro-fracture. In addition, interfacial damage between the matrix and fiber is described as debonding damage. The damage stress and strain concentration tensors are obtained for the elasto-plastic states of the material and are based on the Mori–Tanaka method in the undamaged configuration of the material. The derived concentration tensors are functions of the damage effect tensors and undamaged concentration tensors. As a consequence of damage, the volume fractions in the effective undamaged configuration differ from the initial volume fractions.
