P, T, and SV wave propagation at the interface between solid-liquid media with magnetic field and initial stress in the context of three-phase-lag model

In this article, the problem of reflection and refraction of thermoelastic wave at a solid-liquid interface in the presence of magnetic field and initial stress has been investigated. The problem has been solved in the context of three-phase-lag model of thermoelasticity. The appropriate expressions to find the amplitude ratios for all the three cases of p-wave incidence, SV-wave incidence, and thermal wave incidence have been developed. However, the ratios of amplitudes of reflected and refracted waves to that of incident wave are computed numerically for earth's crust-water interface, for incident SV wave only, considering the initial stress to be tensile as well as compressional both. The obtained results have been presented graphically to show the effect of phase lags, magnetic field, and initial stress.
