Effect of Laser Heat Source on One Dimensional Generalized Thermoelasticity

  Amlendu Kumar,  Shashi Kant,  Neha Mongia

In the present paper, an investigation is devoted to study the induced temperature and stress fields in an elastic half space under the purview of generalized thermoelasticity theory of field equations. The half space continuum is considered to be made of an isotropic homogeneous thermoelastic material, the bounding plane surface being subjected to a Non-Gaussian laser pulse. First we employ the Laplace transform to remove the time dependency of the governing equations. Further, we use the finite element method with respect to space coordinate to obtain the numerical solution in Laplace domain. Finally, a numerical method to invert the Laplace transform is used to obtain the numerical solution in space and time domain. The discussion of results are shown by plotting the different graphs.

Keywords- Thermoelasticity, Laser heating, Finite Element Method, Half Space.
