Earlier, a method was developed by the present author which predicts the elastic moduli of isotropic two‐phase materials with arbitrary phase geometry. The primary scope of the present article is to demonstrate how this method works when used to predict elasticity (Young's modulus) and damping (loss tangent) of porous materials and impregnated materials made of elastic and/or viscoelastic Components. Simple equations are developed which are directly applicable to practical situations. Their qualities are tested successfully against a number of experimental data.
