Propagation of Rayleigh Wave in a Thermoelastic Solid Half-Space with Microtemperatures

Abstract EN

The Rayleigh surface wave is studied at a stress-free thermally insulated surface of an isotropic, linear, and homogeneous thermoelastic solid half-space with microtemperatures.

The governing equations of the thermoelastic medium with microtemperatures are solved for surface wave solutions.

The particular solutions in the half-space are applied to the required boundary conditions at stress-free thermally insulated surface to obtain the frequency equation of the Rayleigh wave.

Some special cases are also derived.

The non-dimensional speed of Rayleigh wave is computed numerically and presented graphically to reveal the dependence on the frequency and microtemperature constants.
