Abstract

The aim of this research is to investigate the thermal and mechanical responses in an isotropic piezo-thermoelastic semi-infinite medium which is subjected to a moving heat source. The exploration has been carried out in the context of two-temperature Moore-Gibson-Thomson generalized thermoelasticity with memory-dependent derivative (MDD). The two-temperature approach is adopted to discern the separate evolution of temperature gradients, while memory-dependent derivative is employed to capture the historical behavior of the material. The resulting system of partial differential equations is systematically solved in the transformed domain of Laplace using state space approach, an advanced mathematical technique. The Fourier series expansion technique for numerical Laplace inversion is used to derive the solution for various thermophysical quantities in the real space-time domain. Parametric studies are conducted to explore the influence of the heat source speed and the parameter related to memory-dependent derivative on the material's response. The outcomes of this work are presented graphically for better understanding of the impacts of the parameters considered. Applications of this work extend to diverse areas including material science, structural engineering and thermal management systems.
