摘要
薄板大位移弹塑性弯曲是几何和材料双重非线性问题。本文采用局部座标系和整体座标系间的转换方法．借助于小变形公式．建立了有限元分析模型，并用此模型对直缝焊管的成型过程进行了模拟．求得了直缝焊管成型的全部过程。计算结果表明，此方法对于薄板的大位移弹塑性分析是十分有效和方便的。
Elastic -platic large displacement bending of thin plates involves material and geometrically nonlinear analysis. In this,the finite element models are obtained by means of translations of coordinate systems and small displacement formulas of thin plates. Analysis of straight seam tube forming process are carried out. The vesulst demonstrate that this method is effictive to analyze elastic-plastic,large displacement bending of thin plates.
