抄録
Based on the interface element proposed for crack propagation problems, a finite element method (FEM) using a temperature dependent interface element is developed. The proposed method is applied to the analysis of the occurrence and propagation of hot cracking in welding. In particular, the hot cracking extending from the starting end of the narrow rectangular plate under bead welding is examined using the proposed method. The following conclusions are drawn. In case of high welding speed with large heat input and small width of plate, hot cracking is likely to occur. This agrees with the phenomena generally observed in elements. The proposed method can simulate not only the occurrence and propagation of hot cracking, but also the contact of the starting edge of the plate after complete cooling.
