THE EFFECT OF MAGNETIC FIELD AND THERMAL RELAXATION ON 2-D PROBLEM OF GENERALIZED THERMOELASTIC DIFFUSION

Generalized magnetothermoelasticity is developed. The formulation is done under two theories: the generalized coupled thermoelasticity theory and Lord-Shulman theory with one relaxation time. A normal mode analysis is performed to obtain the expressions for temperature, displacement components, thermal stress distributions, and concentration of diffusion. The variations of the variables are represented graphically. A comparison is made with the results predicted by the two theories in the presence and absence of the magnetic field
