有限元整体刚度矩阵的一种快速解算方法

The Quick Solution Method of the Whole Rigidity Coefficient Matrix in the Finite Element Numerical Method

根据有限元整体刚度矩阵的特点，提出了快速解算方程的一种方法，通过对程序的运行，可以实现运用常规内存快速计算４０００个节点的有限元计算，并可实现快速解算大型稀疏对称线性方程。

According to the characters of the whole rigidity coefficient matrix in the finite element numerical method,a quick solution method is presented.By running the program,it can quickly calculate about 5 000 joints in the finite element numerical method by only using the base memory of the computer,and this method can be also used in solving the big sparseness symmetric and linear equation.
