Abstract

An elastoplastic constitutive relation of whisker-reinforced composite was derived in Part I of this work [H.Q. Liu, N.G. Liang, An elastoplastic constitutive relation of whisker-reinforces composite for meso damage: Part I – formulation, J. Theoret. Appl. Fracture Mech. 33 (2000) 191–198]. Specific applications of this constitutive equation will be made to address mesoscale damage. Analyzed particularly is the relation between failure surface and dominant mechanism of brittle composites. The damage-induced anisotropy is exhibited using the damage distribution of whiskers in the orientation space. Qualitative agreement is obtained between the prediction and experimental results of carbon/epoxy laminates [S.R. Swanson, Introduction to Design and Analysis with Advanced Composite Materials, Prentice-Hall, Upper Saddle River, New Jersey, 1997].
