摘要
本文通过分析Wilson非协调元内自由度特性,给出了单元内自由度的定义和“均值法”计算公式。在此基础上,证明了Wilson非协调元与协调等参元的对应性,探讨了Wilson非协调元的构造机理。
This paper is concerned with the construction mechanism of Wilson nonconforming element. Through examining the characteristics of the inner degrees of freedom, the definition and the formula of the inner degrees of freedom are given. The average value method is introduced to express the inner degrees of freedom. It is shown that the Wilson nonconforming elements are equivalent to isoparametric elements.
