摘要
在八节点六面体等参单元的基础上在其各个面的法向方向上增加一个自由度 ,同时为了提高精度 ,改善其性能 ,消除几何敏感性 ,又引入七个非协调的内部位移函数和一个泡状函数作为附加位移。数值计算表明该单元的性能良好。
In this paper a normal freedom on each area is given on 8 node hexahedron isopapametric element. At the same time seven unconforming inner displacement functions and one bubble function are adopted as additional displacement in order to eliminate geometry sensitivity and gain high precision. Numerical results show that this element is of excellent properties.
