Abstract: 　　The large deflection buckling deformation of cold rolled strip acted on by residual stress is studied by using 3-power spline function energy method. For many cases of rolled strip’s edge wave, central wave and so on, computation tallies with experiment well, which is satisfying. The paper provides a universal and reliable theory method for studying the large deflection buckling deformation and the critical state losing stability of rolled strip, and theoretical basis for forming the mathematical model of sheet and strip mill’s flatness control.
