Summary
Plane waves in a linear, homogeneous and transversely isotropic thermoelastic body are discussed on the basis of a unified system of governing equations. It is found that the motion influenced by the thermal field takes place in three coupled modes. Explicit expressions for the phase velocities and attenuation coefficients of these modes in the cases of high and low frequencies are obtained. Results valid in the conventional and generalized thermoelasticity theories are recovered as particular cases. Comparison with the corresponding results obtained in earlier works is made.
