2-D Analysis of Generalized Thermoelastic Porous Medium under the Effect of Laser Pulse and Microtemperature

The paper presents the analytical solutions for a generalized thermoelastic medium consisting of microtemperatures and voids subjected to a laser pulse loading the medium thermally. The 0.02 ps pulse duration of the non-Gaussian laser beam is apt for heating a homogenous isotropic elastic half-space. A method called the normal mode analysis is employed to evaluate numerically the effects of various variables such as the micro-temperature vector, variation in the fraction field of the volume, first heat flux moment tensor, temperature distribution on the stresses and displacement components of the medium. In addition, the graphical illustration of the physical response of the medium has been presented in the presence and absence of void parameters, as well as in the presence of laser pulse with two different acting periods.

Automated summary

This paper presents analytical solutions for a generalized thermoelastic medium with microtemperatures and voids subjected to laser pulse loading. The effects of various variables on the stresses and displacement components of the medium were numerically evaluated using normal mode analysis. The physical response of the medium was graphically illustrated in different scenarios, showing significant impacts of the variables on the medium's behavior.
