非線形動的FEM解析の並列計算のための非反復時間積分法

抄録

Demand for the large scale nonlinear FEM analysis is increasing and the efficient computation of such FEM is becoming important. This paper proposes a non-iterative time integration scheme that is applicable to the dynamic FEM analysis, in which the model is partitioned into subdomains for the purpose of parallel computation.
The proposed scheme is implemented as the combination of the explicit scheme and the implicit scheme. Detail of the algorithm of the proposed scheme is described and some aspects of the proposed method such as its stability is discussed based on the numerical study. Applicability of the method is shown by numerical examples of the dynamic analysis of the model which is partitioned into two subdomains. The computation results show the efficiency and accuracy of the proposed method.
