MAGNETOTHERMOELASTIC WAVES IN A ROTATING ORTHOTROPIC MEDIUM WITH DIFFUSION

In this paper, the governing partial differential equations for a rotating orthotropic magnetothermoelastic medium with diffusion are proposed on the basis of the Lord-Shulman theory of generalized thermoelasticity and the velocity equation is obtained. The plane wave solution of this equation is indicative of the existence of four quasi-plane waves, namely, quasi-longitudinal displacement (qLD), quasi-thermal (qT), quasi-mass diffusion (qMD), and quasi-transverse displacement (qTD) waves. The real values of the wave speeds are calculated for a particular material, and the effects of anisotropy, as well as of the diffusion, magnetic, and rotation parameters and the angle of incidence on the speeds are shown graphically.
