In order to solve the large scale structural analysis problems, a finite element solution method called EBE-CG method is presented, which does not require the formation of global stiffness matrix, and then its parallel implementation is discussed.

• 共轭梯度法(CG法)是求解大型稀疏有限元方程组的有效迭代解法。 针对大规模结构分析问题,提出了不形成总刚度矩阵时的EBE-CG法及其并行处理方法。
