一类有效的板弯曲单元

A Family of Efficient Elements for Thin Plate Bending

鉴于Ｉｒｏｎｓ的分片检验条件，在修正势能泛函中引入更一般的广义协调概念，可以推出两种简单易行的板弯曲单元。这类单元总能通过分片检验，而且可以以较少的自由度获得较高的计算精度。

In view of irons patch test condition, a more generalized compatibility condition is introduced into the modified potential energy functional, and two simple and efficient elements for thin plate bending problems are developed in this paper. These elements can always pass the patch test and give high accuracy with less degrees of freedom.
