Modified Moore-Gibson-Thompson Thermoelastic Model with Two Temperatures Effect on Rotating Semiconducting Thermoelastic Solid Cylinder

A rotating semiconducting cylinder is studied within the framework of photo-thermoelasticity. The cylinder is exposed to an exponential pulse, acting as a variable heat flux. The study utilizes the Moore-Gibson-Thompson-Photo-Thermal equations of heat transfer. They incorporate two temperatures to describe the basic equations of the system. The Laplace transform is employed which allows for a more efficient and accurate solution. To calculate the displacement components, carrier density, thermal stresses, and conductive temperature in the physical domain, the numerical inversion techniques are utilized. Furthermore, MATLAB software is employed to generate graphical representations of all the parameters involved in the study. These visualizations illustrate the impact of thermal relaxations and various thermoelasticity theories that consider two temperatures.
