| 抄録 | Based on the interface element proposed for crack propagation problems, a finite element method (FEM) with a temperature dependent interface element is developed. The proposed method is applied to the analysis of the formation and propagation of hot cracking in welding. In particular, Houldcroft type test, Trans-Varestraint test and the narrow gap welding are analyzed using the proposed method. |
