Abstract

This paper is an attempt to understand and define the thermal effects of incident laser radiation on a semi-infinite body. Based on previous research into the subject as well as other research into laser technologies certain assumptions are utilized to facilitate achieving usable solutions. The incident radiation is modeled as a set of independent functions of space and time in cylindrical coordinates. By using the Separation of Variables technique in conjunction with Green's Function a numerical solution to the temperature field induced by the radiation is found. The equations developed while solving the heat conduction problem are then utilized in the analysis of thermal stresses within the body. The Method of Potentials is employed to establish the set of equations necessary to solve for the thermal stresses within the body.
