Magneto-thermoelastic interactions in a photothermal semiconducting medium with diffusion and microtemperatures

The current manuscript is an attempt to investigate the disturbances in a two-dimensional homogeneous, isotropic, magneto-thermoelastic material with mass diffusion, microtemperatures and photothermal effect. The expressions for different physical variables such as displacement, stresses, carrier density, temperature field and microtemperatures are obtained in the physical domain. The formulation is subjected to a thermal load. Normal mode analysis is adopted to procure the exact solution of the problem. Numerical computations have been carried out with the help of MATLAB programming and the results are illustrated graphically. The graphical results indicate that the effects of photothermal parameters, magnetic parameter, diffusion parameters and time are very much pronounced on the field variables. Results of some earlier authors have been reduced as particular cases of the present formulation.
