| 摘 要： | 本文对于迭代法提出一种基本思想类似于多层网格法的快速算法——多层迭代法,并把它初步应用于材料非线性的有限元计算中.计算实例表明:这种方法在加速迭代收敛,减少迭代次数及缩短计算时间上具有良好的效果.

| Abstract: | In this paper, the multistage iteration method-the thought for accelerating the convergenceof iteration which is analogous to that of the multigrld method is presented. Computer examples show this method applied to the nonlinear finite element analysis has good efficiensy for accelerating the convergence of iteration reducing the number of iterative steps and saving the computer time. |
