| Abstract: | In this paper, the parallel algorithm of finite element substructure method has been introduced. By dividing whole structure into many substructures, the concurrent static condensations can be performed in many corresponding CPUs, then the interface displacements can be obtained. Finally the internal point displacements and stresses can be gotten concurrently by substituting back to every substructure. The program of this algorithm has been realized on ELXSI 6400 parallel computer. The results show the computational time can be saved on large-scale. Also the efficiency of this algorithm has been analysed in this paper. |
