Abstract:
This study explores the combined effects of an internal heat source and rotation on a porous solid within the framework of nonlocal thermoelasticity as described by the Moore-Gibson-Thompson theory. By employing a non-dimensional approach, the governing equations were reformulated to highlight the underlying parameters and facilitate a more general analysis of the system. The resulting system of equations was subsequently solved using the normal mode method, yielding analytical expressions that describe the material's displacement, temperature, and stress components. These solutions were further analyzed numerically using MATLAB, and graphical representations were generated to illustrate the effects of internal heating and rotation on the thermoelastic behavior of the porous medium. The findings reveal significant interactions between thermal and mechanical fields, offering deep insights into the performance and stability of advanced materials under complex loading conditions. This work not only advances the theoretical understanding of nonlocal thermoelasticity in porous solids but also provides practical implications for the design and optimization of engineering systems exposed to similar environmental influences.

Thermal expansion and Thermal stress: Problem Solving
To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55 °C.
Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant heat.
