Summary: It is well known that there is an anlogy between wave propagation in a periodically layered (nonhomogeneous) medium consisting of two elastic materials and that in a homogeneous viscoelastic medium. This interesting phenomenon is investigated in this paper. To who the analogy, an attenuation factor of wave is introduced. The attenuation effect of a layered medium is investigated using an exact analogous relaxation function for the layered medium. The effects of the ratio of the two constituent layers, of their mechanical properties, and of the layer thickness on the attenuation of stress wave propagation are examined.
