Springback variational principles for the structures of bar systems and their applications

本文引入了杆系结构的回弹反耦联系统和回弹反耦联方程的概念。应用加权余量法于回弹反耦联方程, 建立了杆系结构的回弹势能原理和回弹余能原理。应用表明, 回弹变分原理为求解杆系回弹变形提供了一个新的途径。

The conceptions of springback anti-coupled systems and equations of the structures of bar systems are introduced in this paper. By the use of weight-residual method on the springback anti-coupled equations, the springback potential energy principle and springback complementary energy principle of the structures of bar systems are established. The applications show that the springback variational principles present a new approach for solving the springback deformation of bar systems.
