| Abstract |
This study investigates the propagation of Love waves in a layered system composed of a
homogeneous thermoelastic layer with an upper rigid surface, resting over a non-homogeneous elastic
half-space. A rectangular-shaped irregularity is introduced at the interface between the thermoelastic
layer and non-homogeneous half space to simulate geometric discontinuity. The governing equations
of motion are formulated using Biot’s theory of elasticity, incorporating the effects of temperature-dependent material behaviour through generalized thermoelasticity. Fourier transformation and perturbation techniques are applied to derive the dispersion relation governing Love wave propagation.
Numerical evaluation of the dispersion relation using MATLAB demonstrates that phase velocity is
significantly influenced by the thermal coupling parameter, inhomogeneity factor, and irregularity
dimensions. The results reveal that the thermal effects, in combination with material inhomogeneity
and rectangular interface irregularities, significantly influence the phase velocity of Love waves.
The present analysis provides theoretical insight into the combined influence of thermal effects and
structural irregularities, with potential applications in geophysical exploration and thermoelastic material design. |
