Abstract:By means of a 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 individual constituents on 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 modeled 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, comments are made on the computational method for determining the overall instantaneous moduli.
