摘要: 本文以L.J.Hayes 1986年的工作[1]为基础,给出了一个有限元结构分析中,当不形成总体刚度阵而计算它与向量乘积的向量化算法。将之用于迭代求解有限元方程组的数值试验结果表明,算法是有效的。

Abstract: In this paper, based on the work of L.J.Hayes in 1986, a vectorized algorithm of the global stiffness matrix-vector multiply in finite element structural analysis is developed when we in fact don't form the global stiffness matrix. A numerical example by using the method in iterative solution of finite element equations verify it is very efficient.
