Relaxation Effects on Plane Wave Propagation in a Rotating Magneto-Thermo-Viscoelastic Medium

The present work aims at investing the propagation of plane magneto-thermo-viscoelastic waves in a homogeneous viscoelastic medium, which is rotating with a uniform angular velocity. Both the coupled dynamical thermoelasticity theory and the generalized thermoelasticity theory are applied to obtain the analytical solution for the phase velocities and the decay coefficients of the plane wave. The numerical values of the phase velocities and the decay coefficients are also computed for a suitable material and the results are presented in graphs. The effects of rotation and the thermal relaxation parameters on phase velocities and decay coefficients are discussed in details for both high and low frequency wave modes.
