THERMODYNAMICAL VIBRATIONS IN AN INITIALLY STRESSED MICROPOLAR MAGNETO-THERMOELASTIC THREE PHASE LAG MODEL WITH LASER PULSE AND TEMPERATURE DEPENDENT PROPERTIES

ABSTRACT

The present research is pertained to study the dynamical interactions in a micropolar magneto-thermoelastic medium under the effect of temperature dependent properties, laser pulse and initial stress. Three phase lag theory is employed for addressing the mathematical analysis. The analytical solution of the displacement components, temperature and stress components is obtained by applying the normal mode analysis technique. Some particular cases are also discussed in the context of the problem. The numerical evaluation of the field quantities is carried out for magnesium crystal like material in the physical domain. The effects of magnetic field and initial stress are observed on the physical quantities and depicted graphically. Some attempts have also been made to explore the three-dimensional responses of the thermoelastic medium. Numerical results predict finite speed of propagation for thermoelastic waves.
