| 摘 要： | 本文对８节点六面体线性等参元和２０节点六面体二次等参元的特性进行了分析和计算。根据三维接触问题有限元解法的特点指出．在三维接触问题有限元解法中，为避免单元特性与接触条件相抵触，只能选用８节点六面体等参元，而不能选用２０节点六面体等参元，并通过计算实例进行了验证。

| Abstract: | The charateristics of hexahedron isoparametric elements with 8 and 20 nodes are analyzed and calaulated in this paper. Results have shown that in FEM to 3D contact problems the hexahedron isoparametric elements with 8 nodes can only be used while the ones with 20 nodes are not so as to avoid contradiction between the charateristics of elements and the contact conditions. This conclusioil has been verified with calculational examples. |
