Thomson Effect on an Electro-Magneto-Thermoelastic Medium under Dual-Phase-Lag Model

Abstract

In this paper, the plane wave propagation, in a homogeneous, isotropic thermoelastic solid in the presence of Thomson effect is studied. The problem is solved in the context of the dual-phase-lag model and Lord and Shulman theory. The heat conduction equation is influenced by the Thomson coefficient. The analytical solution of the problem is acquired by using the normal mode method to obtain the stress components, the temperature and the displacement components. The variations of the field quantities have been depicted graphically in the dual-phase-lag model and Lord and Shulman theory for an insulated boundary. From numerical calculations, the effect of Thomson parameter on a homogeneous, isotropic, electro-magneto-thermoelastic material is revealed and discussed.
