| 摘 要： | 在工程结构力学中，有许多特殊的非线性结构分析计算（如变形、应力、强度），使用传统 的方法难以进行，它们的特殊性在于非线性计算过程产生的有限元刚度矩阵出现病态甚至奇异的 情况，从而导致结构变形、应力、强度等计算无法进行下去。该文提出一个新的分析求解方法，能够 有效处理这些特殊结构分析计算问题。

| Abstract: | In engineering mechanics, some special non-linear structures are difficult to analyze in order to obtain their strength by means of traditional methods. This is because these structures have very ill-conditioned or even singular finite element stiffness matrices. This paper presents a new solution method to deal with the special non-linear problems effectively. |
