Analysis of FGM Rotating Disk Based on Non-Fourier Heat Conduction Model under Electromagnetic Field

In this paper, the thermomagnetic response of rotating disk with functionally graded material (FGM) based on non-Fourier heat conduction model under electrical and magnetic fields is studied. In this study, non-Fourier heat conduction model were considered based on dual phase lag model. Mechanical properties of disk are assumed to follow an identical power law in the radial direction, also the governing equations of rotating disk are derived and then solved through the semi-analytical solution. The results of this analysis are obtained for different boundary conditions, fixed-free, free–free and solid disk. In the present work, the effect of various parameters such as coefficient of heterogeneous material, the intensity of the magnetic field and effects of thermal field on the behavior of rotating disk with functionally graded material is investigated. Finally, the validity of the results by comparing them with the results in previous research is investigated, in which there is very good agreement between the results of the present work and previous studies. The results show that temperature changes is increased with increases in the coefficient of heterogeneous. Also, it is obvious that imposing a magnetic field significantly decreases displacement and stresses and increases stiffness of system.
