The Influence of Anisotropy of the Microstructure on the Overall Elastic-Plastic Response of Fibrous Metal-Matrix Composites

Abstract

By means of consistent homogenization method for obtaining the overall properties of an idealized class of metal-matrix composites with a periodic structure, the influence of anisotropy of the individual constituents of the overall response of the material has been investigated. Two classes of fibers are considered: boron (isotropic) and graphite (transversely isotropic). The plastic induced anisotropy in the matrix is molded by a combined isotropic- kinematic hardening constitutive relation. In addition to a detailed discussion of the effect of the various components of anisotropy on the predicted response of the composite, this paper comprises comments on the computational method for determining the overall instantaneous moduli.
