Memory-Dependent Derivative and Magnetic Field for a Rotating Thermoelastic Medium with Voids under Thermal Loading Due to the Laser Pulse

Abstract

The present investigation deals with the rotation of magneto-thermoelastic solid with voids due to laser pulse and memory-dependent derivative in the context of a three-phase-lag model of generalized thermoelasticity. The bounding plane surface is heated by a non-Gaussian laser pulse and is subjected to prescribed stress. The entire porous medium is rotated with a uniform angular velocity. The normal mode analysis technique has been incorporated to solve the physical problem to obtain the exact expressions for the displacement components, stresses, temperature distribution, and change in the volume fraction field to represent the thermo-physical quantities graphically in the presence and the absence of rotation and magnetic field. The effect of linear and nonlinear kernel function and the effect of the delay-time parameter are also reported.
