EBE技术在结构分析中的应用（Ⅰ）─EBE矩阵向量乘积方法及其实现

APPLICATION OF EBE STRATEGY IN STRUCTURAL ANALYSIS (I)─EBE COMPUTATIONAL METHOD FOR MATRIX-VECTOR MULTIPLY AND ITS PARALLEL/VECTOR IMPLEMENTATIONS

矩阵向量乘积运算是数值分析领域中的一种基本运算。本文基于单元分组技术，提出了在有限元结构分析中，当不形成总刚度矩阵而进行矩阵向量乘积的ＥＢＥ计算方法。该方法不仅预处理过程简单，实现容易，而且其并行化、向量化处理都极为直接。同时，数值试验结果还表明了它的有效性。

On the basis of element's segregation technique presented by us in[4], an EBE computational method, in which the global stiffness matrix needn't be formed, for matrix-vector multiply has been developed in the paper.And then two parallelization/vectorization strategies of the method have been described. Numerical examples i'ndicate the effectiveness of the EBE computational method.
