Energy Ratios

The problem of reflection and refraction of elastic waves due to incident quasi P and quasi SV-waves at a plane interface between the homogeneous and inhomogeneous fibre-reinforced elastic half-spaces has been investigated. The reflection and refraction coefficients and energy ratios of the reflected and refracted quasi P and quasi SV-waves are obtained. These coefficients and ratios are computed numerically for a particular model and the results are shown graphically.

Sample Case

abstract A computer program is presented which calculates Zoeppritz's displacement amplitude coefficients, displacement potential coefficients, and Knott's energy coefficients for plane harmonic elastic waves of P or SV type incident on a plane interface between two isotropic, homogeneous elastic solids. A discussion of these three basic types of coefficients is included. Results of applying the program to a sample case are presented in the form of a graph of the energy coefficients computed for all possible wave types and over a range of angle of incidence of 0° to 90°.
