This article investigates stress and induced temperature in an isotropic, homogeneous, thermoelastic
half-space using a two-temperature generalized thermoelasticity model. The bounding
plane surface of the present half-space continuum is subjected to a non-Gaussian laser
pulse. Laplace’s transform space is considered to deduce a closed-form solution to the problem.
In addition, the inversions of Laplace’s transformations have been carried numerically
to obtain field quantities in the transient state. The effects of parameters of two-temperature,
laser-pulse and laser intensity are investigated. A concluding remark for the graphical forms
of the derived expressions is presented.
