Abstract

The model of the equations of generalized magneto-micropolar thermoelasticity with two relaxation times in an isotropic medium with temperature-dependent mechanical properties under the effect of Hall current is established. Elastodynamic interactions in magneto-micropolar thermoelastic half-space consider the effect of Hall current and rotation subjected to laser heating. The micropolar theory of thermoelasticity by Eringen (1966) has been used to investigate the problem. Normal mode analysis technique is used to solve the resulting non-dimensional coupled field equations to obtain displacement, stress components and temperature distribution. Numerical computed results of all the considered variables are shown graphically to depict the combined effect of the Hall current, laser heat source and rotation. Some particular cases of interest are also deduced from the present study.

Keywords: micropolar thermoelastic, Hall current, thermal laser heat source, rotation, temperature dependence
