Effect of rotation on the surface wave propagation in magneto-thermoelastic materials with voids

Abstract

The present investigation is focused on studying the surface wave propagation in a generalized magneto-thermoelastic materials taking (Green Lindsay) model with voids. The general surface wave speed is derived to study the effects of magnetic field and rotation on surface wave in the presence of voids. In addition the present study can be comprehensively applied to the magneto-thermoelastic medium with voids. The possible non-dimensional frequency of surface wave propagation has been obtained as the solution of an algebraic equation involving a determinant whose elements contain the material parameters, the direction of applied magnetic field and rotation of surface wave propagation. The comparisons for the physical quantities are established numerically and represented graphically in different cases with respect to the used effects.
