Effect of magnetic field and three-phase-lag in a rotating micropolar thermo-viscoelastic half-space homogeneous isotropic material.

This paper is devoted to three-phase-lag theory of thermo-elasticity to study the effects of rotation, ramp parameter and magnetic field in a micropolar generalized thermo-viscoelastic medium. By employing normal mode analysis and Lame's potential theory, the analytical expressions for the displacement components, stresses components, couple stress and temperature field are obtained in the physical domain. Numerical examples are displayed to illustrate the effects of magnetic field, rotation and ramp parameter on the results. When there is no phase-lag effects, the results of the current paper are reduced to exactly the same results available in the literature. However, the magnetic field and rotation have no effect on the non-dimensional temperature. The results indicate that the effect of magnetic field, rotation, ramp parameter, viscous and Phase-lag on the micropolar thermo-viscoelastic medium are very pronounced. [ABSTRACT FROM AUTHOR]
