Wave Propagation on the Boundary Plane of an Anisotropic Body with Inclined Anisotropic Principle Axis.

Abstract

In this paper, SH (horizontally polarized shear) wave propagation in an inclined anisotropic elastic body is investigated. It is analyzed as a basic boundary value problem as the interface between an inclined anisotropic half space and an isotropic half space. Direction of wave propagation is determined by the use of power flow density. It is shown that power flow density determines the direction of the principle axis of an inclined anisotropic body. Reflection and transmission coefficients in the interface are also discussed. The reflection coefficient in the interface is large when inclined angle in large.
