摘要：

The study of propagation of thermoelastic waves in an infinite cylinder has been presented here in the context of Lord-Shulman generalized theory of thermoelasticity. A normalization procedure is presented here for solving multilayer cylinders. A semi-analytical finite element formulation is employed to study the frequency spectra. It is verified by comparing the wave dispersion results for an isotropic copper cylinder with the predictions of the analytical method. Since this method can be used for an anisotropic composite cylinder, numerical results for a silicon nitride and a two-layered (zinc and silicon nitride) composite cylinder are presented as illustrative examples.
