Propagation of Sinusoidal Small-Amplitude Waves in a Deformed Viscoelastic Solid. II

Abstract

The mean energy flux vector for a plane sinusoidal wave of small amplitude propagating in an isotropic viscoelastic material subjected to an initial static pure homogeneous deformation is calculated. The results are applied to the study of the internal reflection of an SH wave at the plane surface of a half-space of such material. They are also applied to the reflection-refraction problem at the plane interface between two half-spaces of such materials, subjected to different pure homogeneous deformations.
