摘要
本文将文[2] 中的联合法,推广到一般的高次变节点 Serendipity 等参单元,较详细地推导出了此类单元的形函数通用公式。该公式运用于 Serendipity等参过渡元的优越性尤其显著。
In this paper,the united method for determining shape function is extended to higher Serendipity soparametric element with variable nodes,and the general formulas of shape functions for the element is obtained.The formu-las show great superiority for the Serendipity isoparametic transitional elements.
