This paper presents two new finite element methods for the elastic-plastic analysis of structures, hybrid/mixed non-conforming finite element methods. The assumed-stress hybrid functionals with incremental forms are modified by using the experience of field functional separation for reference, so the inversing of a high matrix is simple to handle and the computing efficiency and the convergent exactitude for the non-linear finite element analysis of variables are increased.This paper also presents a hybrid/mixed...

This paper presents two new finite element methods for the elastic-plastic analysis of structures, hybrid/mixed non-conforming finite element methods. The assumed-stress hybrid functionals with incremental forms are modified by using the experience of field functional separation for reference, so the inversing of a high matrix is simple to handle and the computing efficiency and the convergent exactitude for the non-linear finite element analysis of variables are increased.This paper also presents a hybrid/mixed non-conforming quadrilateral for the elastic-plastic plane problem. At last, numerical results are given by comparison 'of experiment results and Rcfs [3]. The results show that the methods in the paper are very efficient in the elastic-plastic analysis.

本文提出两种结构弹塑性分析的有限元方法——杂交/混合非协调元法。该法采用场变量分解,文[1]对增量形式的杂交应力元能量泛函进行修正,简化了高阶矩阵的求逆运算,从而提高了多变量非线性有限元分析的计算效率和收敛精度。文中按文[2]给出的第二种能量泛函的修正形式建立了弹塑性平面问题中的杂交/混合非协调四边形单元。最后给出算例,并与实验解及文[3]解进行比较。表明该方法分解弹塑性问题是十分有效的。

This paper proposes a method of record-column for decomposition of singular matrix. The method for every singular matrix A has a simple decomposition into the product of a column full rank matrix and a row full rank matrix. Therefore, we can correctly obtain a nonsingular matrix D only containing whole non-zero eigenvalues of A, so that the calculations for its determinant of eigenmatrix may decrease to the lowest order, and the computational quantities may be reduced. Finally, the method is extended to the...

本文首次提出了奇异矩阵分解的记录列方法。该方法可以容易地将任一奇异矩阵A分解为一列满秩阵与一行满秩阵的乘积,因而能直接得到一个恰好包含A的全体非零特征值的非奇异阵D,使特征矩阵的行列式计算降至最低阶,以减少计算工作量。最后将该方法推广到列不满秩的高矩阵(即行数大于列数)的情形,给出了亏秩平差计算中的一个实例。
