| 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. |
