Strength Evaluation of Arc Welded Joints Using Fracture Prediction Model Based on FE Analysis
A finite element analysis (FEA) model for predicting the weld fracture is developed using the local plastic strain together with the stress triaxiality σm/σbar (σm: hydrostatic stress, σbar: equivalent stress) as fracture criterion. In this study, this FEA model is applied to tension tests of arc welded joints, and is examined the influence of welding wires on joint strength and fracture locations. FEA results show good agreement with experimental results of joint strengths and fracture locations. This method enables clarification of the arc weld fracture phenomenon and the accurate fracture prediction.
