Body wave propagation in rotating thermoelastic media

The present paper deals with the propagation of body waves in a homogenous isotropic, rotating, generalized thermoelastic solid. The complex cubic secular equation has been solved by using Cardano's and perturbation methods to obtain phase velocities, attenuations and specific loss factors of three attenuating and dispersive waves, which are possible to exist in such media. These wave characteristics have also been computed numerically for magnesium crystal and are presented graphically. Statistical analysis has been performed to compare the computer simulated results obtained by using both methods. This work may find applications in geophysics and gyroscopic sensors.
