%X The differential equations about shear and bulk moduli of foam plastics have been derived by differential scheme of composite mechanics. And the couple equations have been solved by using the relation of elastic constants for isotropic foam plastics. The relationships between shear modulus and bulk modulus as well as shear modulus and porosity of material have been obtained theoretically. Finally, both Young's modulus and Poisson's ratio in relation with porosity have also been determined. The comparison between the present model and other models has been made graphically.
