The rolled strip was divided into a number of strip elements,and the deflection function model was constructed with the third-power spline function and the sine function.Using the minimum potential energy principle,the shape discrimination was transformed into the solution of characteristic values.The influence of different elements on the shape stability of rolled strip was discussed.
