摘要
利用有限元分析的“双参数”法，通过适当选取形函数空间中的高阶项，构造了一类对称的十二参矩形板元．同时证明该类矩形板元通过广义分片检查。
In this paper, by using double set parameter method of finite element analysis and choosing suitable high order terms of shape function spaces, a class of symmetrical 12 parameter rectangular plate elements is presented. It is proved that those elements pass through generalized patch test and are convergent for general fourth order plate problems. The optimal error estimates are given.
