And, springback of member bar and straight beam is simulated by finite-element program software ANSYS. Both of the springback energy theory and the finite-element method are verified by a springback test of simply supported beam.

• 将其结果和用有限元通用计算程序ANSYS软件对杆件和直梁的回弹进行模拟计算的结果加以比较，以及通过做一个简支梁的回弹试验来验证回弹能量原理及其有限元法的正确性。
