大挠度弯曲薄板的回弹有限元分析

Springback finite-element analysis for large deflection of bending thin plate

通过引入有限变形回弹反耦联系统和反耦联方程的概念,由回弹势能原理建立了板成形的大挠度回弹有限元法。并应用此方法对板的成形回弹进行模拟计算,将计算结果与实验结果进行了比较。

This article first introducing the non-coupled systems and non coupled equation of finite deformation springback. The method of springback finite-element for large deflection of plate shaping is established on springback potential energy principle that is already concluded. The shaping springback of plate is simulated by applying the method and we have compared simulation result with test result.
