| 摘 要： | 本文用壳中面节点的位移矢量和节点处壳中面单位法线矢量的矢端位移矢量构造了一种大变形曲壳单元,它是大变形曲壳单元的一般形式,能包括已有的大变形曲壳单元,且公式最简单,计算中采用的载荷增量或位移增量可以很大。

| Abstract: | This paper presents large deformation curved shell elements. The displacement field at a point P(ξ, η, ζ) within an element is discribed, using the vectors Ut and the Ft. The Ui is the displacement vector of node i in mid-surface of shell, the vector F4 is the displacement vector of the end of the unite normal vector at node i. The formulation of the elements is general and simpler than existing ones, and unlimited in the load or displacement increments |
