ABSTRACT
An approximate method for the determination of temperature and stress distributions in an elastic half-space heated by a laser impulse on its boundary is derived. The method is based on the solutions for two cases of laser time structure: sectionally constant and sectionally linear. Piecewise-constant and piecewise-linear finite functions are used for approximation of the temporal profile of analyzed laser impulses. Numerical results are presented for typical lasers found in engineering practice.
The investigation described in this article is a part of the research project No. W/WM/1/04 realized at Bialystok University of Technology.
