| 摘 要： | 1980年以来,唐立民等提出一种拟协调元法,用来构造椭圆型方程的离散格式.粗略地讲,该法将每个单元上的能量表达式所含导数项的面积分(假设问题二维的),用格林公式转化为单元边界上的线积分,然后采用某种数值积分,将线积分进行离散.对只含函数项的面积分,也用相应的数值积分进行离散.用此法计算单元刚度阵,比较简单、灵活.

| Abstract: | It is proved that the internal displacement field of the 9-parameter quasi-conforming plateelement, defined by Zhang Hong-qing and Wang Ming througn a very complicated procedu-re, is nothing but the usual Zienkiewicz's incompatible cubic element. It is also shown thatthis quasi-conforming element is closely related to the TRUNC element, recently developed byArgyris et al. |
