| 摘 要： | 研究一种基于ＰＶＭ的弹塑性子结构并行有限元法。利用多个波前，对各子结构并行地进行静凝聚。再采用预条件共轭梯度法（ＰＣＧ）并行求解界面方程。算例表明该方法能获得较好的并行加速比，同时也能有癣地节省内存量。

| Abstract: | In this paper, a elasto plastic substructure parallel Finite Element Method based on PVM is studied. All substructures are condensed with multifronts in parallel, the displacements of interface nodals are obtained parallely with Preconditioned Conjugate Gradient (PCG) method. Example shows the method can achieve better parallel speedup ratio, and it can save the storage efficiently. |
