摘要

In this paper, an estimation is made to study the propagation of Stoneley waves in magneto-thermoelastic materials with voids and two thermal relaxation times in the context of a Green-Lindsay model. The basic governing equations have been formulated in the xz-plane and the magnetic field is considered in the y-axis, which acts perpendicular to the wave propagation. We applied Lame's potentials method to solve the problem. The boundary conditions that the continuity of forces stresses, Maxwell's stresses components, displacement components, heat flux, temperature and volume fraction field are illustrated at the interfaces between two dissimilar half-spaces to obtain the frequency equation of the Stoneley waves in the media. Some special cases neglecting: (i) the magnetic field, and (ii) the thermal relaxation times' parameters are deduced as special cases from this study and the numerical results are displayed graphically.
