抄録

Finite element method is a powerful tool for predicting welding distortion. However, the mechanical phenomena in welding are strong non-linear transient problems and thermal-elastic-plastic FE analysis requires very long computational times. To overcome this problem, an interactive substructure method is developed as a method to reduce the computational time in three-dimensional analysis. In this paper, in order to confirm calculation efficiency for a large scale problem, calculation of the pipe model with 538,200 degree of freedoms is performed. Further, calculation of the residual distortion in engine component is performed and its applicability for practical problems is demonstrated.
