Effect of Hall Current on Generalized Magneto-Thermoelasticity Micropolar Solid Subjected to Ramp-Type Heating

  • Published:
International Applied Mechanics Aims and scope

The problem of two-dimensional magnetic micropolar generalized thermoelastic medium in the presence of the combined effect of Hall currents subjected to ramp-type heating is investigated. The medium is permeated by a strong transverse magnetic field imposed perpendicularly on the displacement plane, the induced electric field being neglected. Ohm’s law is modified by including two terms, one for the cross product of the current density and the initial magnetic field and the other for the cross product of the velocity and the initial magnetic field. The Laplace and exponential Fourier transform techniques are employed to transform the governing partial differential equations to ODE, which are solved exactly. Comparisons with the previously published work are conducted and the results are found to be in good agreement. The distributions of the temperature, displacement, stress, microrotation, and current density are obtained. The numerical values of these functions are represented graphically
