Paper Abstract

The mechanism of original crack formation on cylindrical shells with inner-pressure and under laser beam irradiation was investigated. By high-speed photographer, it was found that the crack formed at the central area of the surface irradiated by laser beam. The mechanism of crack formation was examined and discussed on the base of fractography, metallographic inspection and stress analysis. A simple criterion is setup to judge the original crack formation on the shell irradiated by laser beam. All information provided here is conductive to a better understanding of this problem.
