Circular Waves in Thermoelastic Plates Sandwiched between Liquid Layers

Abstract

This paper examines in detail the characteristics of the
propagation of thermoelastic waves in a homogeneous, transversely
isotropic, thermally conducting elastic plate bordered with layers (or halfspaces)
of conducting viscous fluid on both sides. Complex secular
equations for symmetric and antisymmetric wave motion of the circular
plate, in completely separate terms, are derived. The waves of short wavelength and Leaky Lamb waves have also been discussed. The results have been deduced and compared with the existing one in relevant publications available in the literature at various stages of this work. Finally, in order to illustrate the analytical results, the numerical solution is carried out for cobalt plate bordered with water by using the functional iteration method. The analytical and numerical results are found to be in close agreement.
