In this paper, the thermoelastic interactions in an orthotropic unbounded body containing a cylindrical cavity are studied. This problem is solved by using the Green and Naghdi's (GN) generalized thermoelasticity model. The thermal material characteristic of the GN theory is taken as linear function of temperature. The surface of the cylinder is constrained and subjected to an exponentially decaying pulse boundary heat flux. The Laplace transform is used to remove the time dependency from the governing field equations. Finally, the transformed equations are inverted by the numerical inversion of the Laplace transform. Numerical results are shown graphically to estimate the effect of the thermal material coefficient and time of the pulse heat parameters. The distributions of all the studied felids in the space-time domain are also investigated.
