N2 - Closed-form constitutive relations are given for the prediction of the overall response of unidirectional fiber-reinforced composites having constituents that are elastoplastic materials. In these equations the damage mode of imperfect bonding between the fiber and matrix phases is incorporated. The interface decohesion is represented by two parameters that completely determine the degree of adhession at the interfaces in thenormal and tangential directions. Perfect contact, perfectly lubricated contact, and complete debonding are obtained as special cases. In the elastic region, the average stress-strain relations are given in terms of the effective elastic moduli of the damaged composite, all of which are given by closed-form expressions. The derived constitutive equations can be readily implemented for the analysis of metal matrix composites.
