SELF-CONSISTENT ANALYSIS OF ELASTIC-WAVE PROPAGATION IN 2-DIMENSIONALMATRIX-INCLUSION COMPOSITES

We present an elastodynamic effective-medium model for the calculation of the effective properties of a two-dimensional composite material c onsisting of an isotropic sheet with isotropic circular inclusions. Ou r model is used to calculate the in-plane transversal elastodynamic pr operties of a three-dimensional material reinforced with infinitely lo ng cylindrical fibres. We compare these results with those of an analo gous model for the transverse properties of a three-dimensional system with aligned spheroidal inclusions of finite length. The two sets of results are qualitatively similar but differ in quantitative details.
