它与三节点等参轴力杆单元组合时可以精确地模拟薄壁结构中杆与蒙皮之间的剪流作用。

Combining with three nodes isoparametric axial force element, the new element can be used to accurately calculate the shear flow action between bar and skin in thin-wall structure.

What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.

组合成为有意义的单元,那么这就让我们回到,一开始讲的话题之一了,这就是抽象的概念,也就是我可以以一个简单的，实体的形式创建这样的一个单元，把具体实现隐藏然后写一些,真正模块化的代码,我们在以后的课程中。
