摘要
本文证明具有旋转周期对称性的结构，在对称适应的坐标架下，其虚边界元方程的系数矩阵具有块循环的形式，给出一种分解算法（即将原问题分解成一系列相互独立的子问题的求解法），适于任意形式的载荷分布。
It is proved that the global coefficient matrices of the virtual boundary element equations for the ro tationally periodic symmetric structures are block circulant, so long as a kind of symmetric adapted reference coordinate system is adopted. Furthermore, an efficient algorithm, which leads to the partition of the original problem into a series of subproblems, is proposed. The method permits arbitrary load distributions for stress analysis problems.
