ELECTROMAGNETIC EFFECTS ON RAYLEIGH SURFACE WAVE PROPAGATION IN A HOMOGENEOUS ISOTROPIC THERMO-MICROSTRETCH ELASTIC HALF-SPACE
The paper deals with the problem of electromagnetic effect on the propagation of the Rayleigh surface waves in a homogeneous, isotropic, thermally-conducting microstretch elastic half-space. In this context, the generalized theory of thermoelasticity is considered. The governing equations for the Rayleigh surface waves in the cases of insulated, as well as isothermal, boundaries are derived. In the presence of the magnetic effect, the analytical expressions for the displacement, microrotation, microstretch, and temperature changes are obtained. The changes in the phase velocity, microrotation, and path of particles for aluminum epoxy material are presented graphically. Keywords: Rayleigh surface wave, electromagnetic effect, microrotation, microstretch.
