Rayleigh-type surface waves in a nonlocal thermoelastic solid half space with voids

The present paper deals with the propagation of surface waves in an isotropic and homogeneous nonlocal generalized thermoelastic solid half-space with voids. The dispersion relations for Rayleigh-type surface wave are derived for both thermally insulated and isothermal boundaries. The non-dimensional wave speed of Rayleigh-type surface wave is computed for some specific constants of a material representing the present model. The dependence of non-dimensional wave speed on frequency, nonlocality, thermal and voids parameters is illustrated graphically.
