PROPAGATION OF THE RAYLEIGH WAVE IN AN INITIALLY STRESSED TRANSVERSELY ISOTROPIC DUAL-PHASE-LAG MAGNETOTHERMOELASTIC HALF-SPACE

The  basic  equations  for  the  wave  on  the  surface  of  an  initially  stressed  transversely  isotropic  dual-phase-lag  thermoelastic body subjected to the action of a magnetic field were solved. Particular solutions were applied to the thermally insulated free surface of a half-space to obtain the frequency equation for the Rayleigh wave. This equation was approximated for calculating the numerical values of the dimensionless velocity of the Rayleigh wave. The Rayleigh-wave velocity was represented graphically for the cases of coupled, Lord–Shulman, and dual-phase-lag thermoelasticities. The influence of the dual-phase-lag and the initial stress of a body, the value of the magnetic field, and the frequency of the Rayleigh wave on the velocity of this wave were determined.
