The impacts of variable thermal conductivity in a semiconducting medium using finite element method

Abstract

In this paper, the effect of variable thermal conductivity under generalized photothermoelastic theory in semi-conductor medium is studied. The numerical solutions of the problem are presented by the finite element method under the effect of the uniform unit step temperature on the surface of the medium. A comparison between the numerical results and the previous analytical studies are obtained by others by neglecting the new parameter and the behaviors of physical quantities for the numerical solutions are examined to confirm the accuracy of the proposed method.
