| Abstract: | Springback principle of minimum potential energy for straight beam formed by bending was applied to calculate the springback of straight beam bending. Solving formulae of the finite element method for calculating springback of straight beam bending were established, the finite element program was compiled for calculating springback of formed beam with simply supported end, the beam was applied concentrated loads. The calculated results of the program were contrasted with the results from other methods. From the comparison of the results, it is concluded that springback principle of minimum potential energy for straight beam formed by bending and its finite element methods are right. |
