Recently, the laser processing is widely applied in the various fields of the industrial production. Especially, fusing, welding, trimming and so on have already been well known. However, the bending of the thin plate by the laser processing is hardly known. As the first step of this study, the single irradiation that is the most fundamental case is considered in this paper. The limit analysis combined loading of the membrane deformation and bending deformation is carried out by using the radial flow rule as the plastic flow rule. Moreover, the distribution of the deflection under the plastic deformation and spread of a plastic region, which grows in the neighborhood of the irradiation portion, are being examined.
