EFECTIVE MEDIUM THEORY IN ELASTIC PROPERTIES OF ISOTROPIC COMPOSITE MATERIALS

In this paper we first review a recent effective medium theory for composite materials properties.It is then suitably extended for the description of the elastic properties of isotropic binary composites.The formulation is used to study the shear modulus of a ccmposite with a dispersion of spheres,srecializing to the limiting cases of rigid and soft inclusions.Exact formulas for the two cases are obtained and compared with known experimental results.
