A research program for investigating the elasto-plastic behavior when a laser beam was irradiated to the surface of a thin metal plate with cooling its backside is described in this paper. Since the residual deformation and the residual internal force occur in a thin plate after the cooling process, the plastic analyses for the second and third irradiation are more complicated. Based on the radial flow rule, the increments of internal force and deformation can be decomposed into an elastic component and plasticity component on the interaction curve. The numerical analyses for the third irradiation are carried out in this paper, and the distributions of the internal forces at re-yielding and at the end of the heating process of the third irradiation are made clear.
