curvature form

Based on analyzing the mechanism of laser peen forming(LPF),a theory of pure bending with small deflection of metal sheet induced by laser peening was presented,the estimated formula of sheet deformation curvature after LPF was derived,and the mathematical model among radius curvature of deformation,depth of residual stress and the material property was established.
