摘要：

This paper presents a paralleled element-free Galerkin (EFG) algorithm to analyze the structure with cyclic symmetry. The global EFG equation system is proved to be block-circulant under a corresponding symmetry-adapted coordinate system, and is partitioned into a number of smaller independent sub-problems, which are solved simultaneously on a multiprocessor parallel computer in parallel virtual machine. Numerical examples are given to illustrate the correctness, speedup, and efficiency of the proposed algorithm.
