Abstract

A solution of a thermoelastic problem dealing with the effects of the radiation generated by a repetitively pulsing laser directed toward a thin thermoelastic layer bonded to an inert semi-space is presented. Both the thermoelastic potential method and the Love stress function are employed. The temporal variation of each pulse is modeled mathematically as a function with three constants, while the radial intensity distribution of each pulse is taken as a Gaussian distribution. Results are presented in the form of graphs.
