| 摘 要： | 本文介绍的四边形组合单元是一种由四个二次型三角形单元拼装而成的基本单元。在拼装过程中凝聚掉五个内节点,形成8节点二次型四边形单元。它具有精确、连续的优点,又避免了存贮量和运算量的大量增加。对复杂边界条件情况,虽然它不如具有曲线边的等参单元拟合得好,但由于工作量的明显减少,故仍然具有实用价值。

| Abstract: | The basic element recomended in this paper is a quadrilateral element assembled by four 6-node triangular elements. Five internal nodes are eliminated by condensation during the assemblage. As a result a 8-node quadrilateral element is constructed. It has good continuity and accuracy. Compared with 8-node isoparametric element, less computer time is required. |
