RESUMO

A method for calculation of effective elastic moduli of granular composites that is based on the model of elastic deformation of porous materials is suggested. A specific feature of this method is averaging of microscopic stresses and deformations over the effective volume of phases rather than over the total volume of phases. The calculated dependences of effective volumes of averaging on elastic moduli and volumetric content of phases are obtained. The results of calculation are compared with the experimental data in different combination of elastic moduli with an arbitrary volume concentration of phases.
