摘　　要：针对平面四节点单元进行数值研究,利用Matlab语言编制有限元程序,并以大变形问题为例对不同长宽比的单元进行计算对比。数值研究表明该单元的长宽比对大变形问题计算的影响较小,该单元对大变形问题具有较好的适用性。Aiming at the flat surface four node unit proceeding numbers study, it makes use of the Matlab language establishment the limited a procedure, and with big transform the problem for an unit different long to breadth ratio comparing calculation contrast, the number research expresses the long to breadth of that unit the ratio to big transform the calculating influence in problem smaller, unit to big transform the problem have the good adaptability.

关 键 词：基线力 边中节点 长宽比 大变形
