多分辨率样条平面单元

MULTIRSOLUTION SPLINE PLANE ELEMENT

  • 摘要: 本文给出了多分辨率单元的基本概念,并以分段二次 B 样条函数为尺度函数建立了一种多分辨率平面单元。这是一类低阶、精度可调整的协调位移型新单元,可用于自适应有限元分析。参照本文的方法与过程可建立其它的一维、二维和三维多分辨率单元以及多分辨率板壳单元。

     

    Abstract: In this paper, the basic concept about multiresolution element is presented. Taking the piecewise quadratic B-spline as the scale function, a multiresolution plane element is developed. This is a class of low order, precision adjustable conforming displacement element. It can be used in adaptive analysis. According to the method and procedure in this paper, other one two-or three- dimensional multirsohition element and multirsofution plate/shell elements can be developed.
