Theory of elastic waves in real crystals. I

  • Published:
Soviet Physics Journal Aims and scope

Abstract

A new approach to the description of wave processes in real crystals is described; in this approach, the equations of motion of a continuous medium are written as a system of first-order partial differential equations interms of the displacement vector. Some consequences which do not follow directly from the initial equations of motion are analyzed. It is shown, in particular, that the boundary conditions for the displacement field may be obtained directly from the processed equations. The analogy with electromagnetic waves is briefly discussed.
