C°连续有限元形函数的系统公式

The Systematic Formulas of the Shape Functions for C°-continuity Finite Element

本文给出构造Ｃ°连续有限元形函数的系统方法。通过递推的方式，由低次单元的形函数导出高次单元的形函数，从而使Ｃ°连续有限元形函数的构造过程系统化、程序化。

The systematic method for forming the shape functions of the C°-continuity element is given. By way of recurrence, the shape functions of high-order element are obtained from those of low-order element. The course for forming the shape functions of the C°-continuity element is systemized.
