用权残法构造混合梁元的对称矩阵

THE SYMMETRY MATRIX OF THE MIXED BEAM ELEMENT CONSTRUTED WITH WEIGHTED RESIDUAL METHOD

    摘要
  • 摘要: 本文采用文献5的插值函数,改变权函数的选择,构造了对称刚度矩阵;于是,在计算时可采用对称矩阵的熟悉技巧,使解题规模得到扩大。如采用通常的有限元装配方法,可解决梁杆结构问题。从计算的例题看到均有高精度的结果。

     

    Abstract: In this paper, the symmetry matrix has been constructed by the use of the paper5 with the change of the selected weighted Functions, so the familiar techanique of the symmetry matrix can de applied, and the solved scope can be expanded. lt can solve the problems of the system with the bars and beams. lf the assembling methods are used. The good precision results are obtained for examples.
