Rayleigh waves in magneto-thermoelastic rotating media with thermal relaxation

Abstract

Following a linear theory of magneto-thermoelasticity with thermal relaxation, the propogation of Rayleigh waves in a semi-infinite, homogeneous, isotropic, electrically and thermally conductiong body permeated by a magnetic field parallel to the boundary surface is investigated. It is assumed that the entire elasitic medium is rotating wih a uniform angular velocity. Frequency equation is obtained and is analysed for small and large values of the frequency and large values of spin velocity and the magnetic field. The dependency between the angular frequency and the surface wave speed is graphically shown.
