| Abstract: | 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. |
