| Abstract |
This study presents an analytical and numerical investigation of the dynamic response of a thermoelastic slab, based on the Moore-Gibson-Thompson (MGT) theory, sandwiched between two identical elastic half-spaces. The thickness of the slab is assumed to be 2h. The primary objective is to examine how different thermoelastic models influence wave propagation, stress distribution, and temperature evolution under mechanical loading. The governing equations are solved using the normal mode analysis technique, and numerical simulations are performed to validate the theoretical results. A comparative analysis is conducted among the Biot Classical, Lord-Shulman (LS), Green-Naghdi Type III (GN-III), and MGT models. The results reveal that the MGT theory more accurately captures the finite speed of thermal waves and provides smoother stress and temperature profiles, emphasizing its suitability for modeling complex thermoelastic phenomena in layered structures. |
