Abstract
In the present paper, the Rayleigh wave in a generalized thermoelastic solid half-space is considered with impedance boundary conditions. The governing equations of homogeneous and isotropic generalized thermoelastcity are solved for general surface wave solutions. The general solutions in the half-space satisfy the required radiation conditions. These solutions also satisfy the required impedance boundary conditions at the free surface of the half-space to obtain the secular equation for wave speed of Rayleigh wave for the cases of thermally insulated surface and isothermal surface. The non-dimensional wave speed is computed for a relevant material data to observe the effects of impedance parameters and frequency.
