一个双参数十二参矩形板元

A 12-PARAMERTER RECTANGULAR PLATE ELEMENT WITH TWO SETS OF PARAMETERS

本文利用“双参数有限元方法”，构造了一个新的十二参矩形板元，证明它通过Ｆ－Ｅ－Ｍ－Ｔｅｓｔ和广义分片检查，因而对一般四阶板问题均收敛，同时还给出了它的一些变形及相应能量误差和Ｌ￣２—误差估计。

This paper presents a new 12-parameter rectangular plate element by using finite ele-ment method with double sets of parameters.It is proved that this element passes through F-E-M-Test and generalized patch Test and it is convergent for general fourth-order plate problems.Someother forms and energy error estimation and L￣2-error estimation are given.
