证明偶次Argyris型元适定性的新方法

A New Method for Proving the Well-Posedness of Even Order Argyris Type Triangular Elements

由于偶次(6次)的Argyris元自由度较多,导致其适定性的验证比较繁琐.通过建立新的坐标系,给出了一个验证其插值适定性的简单方法,并可推广到更高次的情况.

For even order Argyris type triangular element(order six),the verification of well-posedness is a complex question,because this element has more freedom degrees.By establishing the new coordinate system,a simple method is developed to prove the well-posedness of the interpolations and this method can be generalized to the higher order Argyris elements.
