A Numerical Simulation to the Deformation of an Internally Pressured Cylinder Tank under Intensive Laser Irradiation

When intensive laser beam irradiated on a cylinder tank wall, bulge and rupture will take place at the area laser loaded. In this paper, the finite element method is used to simulate the deformation. The stress and strain field calculations predict that the center of the laser beam irradiated region is the most dangerous where rupture will take place. This result is in good agreement with the experiment.
