Magneto-thermoelastic interactions in a photothermal semiconducting medium with diffusion and microtemperatures (Q6541661)

The authors investigate the dynamical interactions in a two-dimensional homogeneous, isotropic, magneto-thermoelastic semiconducting material with mass diffusion, microtemperatures and photothermal effect, in the presence of an initial magnetic field and within Lord and Schulman theory of extended thermodynamics. A surface thermal load is applied to the boundary.\N\NThe governing equations and the constitutive relations are presented in a system of orthogonal Cartesian coordinates, and the solution of the problem for a half-space is obtained by normal mode technique under appropriate boundary conditions, viz. free traction, vanishing heat flux and concentration, in addition to a prescribed temperature distribution.\N\NParticular cases are examined, and numerical results and plots are provided and discussed for concrete values of the material and geometrical parameters, in order to assess the effect of the thermodiffusive constant, the photothermal and magnetic parameters on the behavior of the solution. Former results are obtained as special cases.\N\NConclusions are summarized in a final section to emphasize the applicability of the presented model.
