Abstract: Dispersion relations for a coupled thermoelasticity problem including a hyperbolic heat conduction equation are derived, and their asymptotic analysis is performed. Dependences of the wave number and characteristics of the vibration damping rate on frequency are obtained and compared with similar diagrams in the classical model.

Keywords: hyperbolic thermoelasticity, dispersion relations, characteristics of the vibration damping rate, wave number, asymptotes.
