Abstract
A corrected solution of the stress and strain distribution problem around a single spherical elastic inclusion in an elastic body is presented. Subsequent ly, by an appropriate selection of boundary conditions and elastic energy balance equations, the stress and strain distribution in a composite material, consisting of a matrix and regularly arranged spherical particles, is approx imated. In the result the Young's modulus and the Poisson's ratio of the composite considered as a continuous medium is obtained. These values are presented graphically as a function of the elastic properties and concentra tions of both components. A partial experimental verification of the theoretical calculations, based on some published experimental results of other authors as well as experiments performed especially for this purpose, has been carried out. A good agreement with the presented theory has been achieved.
