Abstract:
This paper explores the behavior of time-periodic plane waves as they movethrough an unbounded nonlocal thermoelastic medium that contain voids. Theanalysis identifies the existence of three distinct types of coupled compressionalwaves and separate shear wave, each travelling at unique velocities. All wavetypes demonstrate dispersive characteristics, meaning their speeds depend onfrequency. However, the compressional (dilatational) waves exhibit attenuation,while the shear(transverse) wave propagates without loss of amplitude. Thepropagation of the compressional waves is significantly affected by the presenceof voids, thermal effects, and the material's nonlocal elastic response. Incontrast, the transverse wave is influenced only by the non-local elastic behaviorand remains unaffected by voids and thermal factors. For a specific theoreticalframework, numerical simulations have been conducted to assess how variablessuch as wave frequency, porosity, thermal coupling, and nonlocal elasticityimpact the wave speeds, attenuation rates, and energy dissipation characteristicsof each wave mode. The resulting data are illustrated through graphs andthoroughly interpreted.
