Abstract

An algorithm based on finite elements applied to digital images is described for computing the linear elastic properties of heterogeneous materials. As an example of the algorithm, and for their own intrinsic interest, the effective Poisson's ratios of two-phase random isotropic composites are investigated numerically and via effective medium theory, in two and three dimensions. For the specific case where both phases have the same Poisson's ratio (v1 = v2), it is found that there exists a critical value v*, such that when v1 = v2 > v*, the composite Poisson's ratio v always decreases and is bounded below by v* when the two phases are mixed. If v1 = v2
