Propagation of Elastic Waves in Two-Component Media - USSR _.

Abstract

To date a number of works have been devoted to the dynamics of two-component media; for example, Ya. I. Frenkel' I), Kh. A. Rakhmatulin 2, Biot 3,4, and Zwicker and Gostain.5, However, the basic problem regarding the construction of equations of motion of two-component media has still-not ultimately been solved but requires additional study and experimental checking. Below we shall examine the simplest case of movement propagation of elastic waves in a homogeneous isotropic medium, consisting of solid and liquid components. The problems of the reflection of plastic waves and of surface waves on the free boundary of a semi-space were solved. It was shown that the relationship between stresses and deformations established by Ya. I. Frenkel' is equivalent to a similar relationship established by M. A. Biot, while the equations of motion of the latter are the more common.
