Specific heat and magnetic effects in orthotropic piezoelectric micropolar medium under three-phase-lag thermoelastic model

Abstract

This paper investigates the nature of physical variables and phase speed of elastic waves in the heat conducting orthotropic magneto-micropolar piezoelectric material under the three-phase-lag model. Using normal mode analysis and appropriate boundary conditions, we obtain the expression of these physical variables of the material. It is evident that five elastic waves can propagate through such a continuum material. The physical variables and phase speed of elastic waves are computed numerically. The effects of magnetic intensity and specific heat of the material on these variables and phase speed are illustrated graphically. Two-dimensional graphs which are of sinusoidal form and three-dimensional graphs of these physical variables are also presented.
