Effect of initial stress and rotation on magneto-thermoelastic material with voids and energy dissipation

Purpose - The purpose of this paper is to study the effect of rotation and initial stress on magnetothermoelastic material with voids heated by a laser pulse heating. Design/methodology/approach - The analytical method used was the normal mode analysis technique. Findings - Numerical results for the physical quantities were presented graphically and analyzed. The graphical results indicate that the effect of rotation, initial stress and magnetic fields are observable physical effects on the thermoelastic material with voids heated by a laser pulse. Comparisons are made with the results in the absence and the presence of the physical operators, also at various times. Originality/value - In the present work, the authors shall investigate the effect of the rotation, initial stress, magnetic field and laser pulse on thermoelastic material with voids subjected to a laser pulse heating acting as a thermal shock. A comparison is also made between the two types (types II and III) of Green-Naghdi theory in the absence and the presence of the physical operators. Such problems are very important in many dynamical systems. © Emerald Publishing Limited.
