Abstract
Operators of V-bending process have sometimes been injured because of broken piece of a die. To prevent this accident, a structure of the die that is tough to break is required. According to the previous study, introducing a hole in the V-bending die reduced stresses at the bottom of V-groove. Therefore, parametric study of a hole in a structure is necessary to find an appropriate design of the structure. However, parametric study of a structure with a hole using conventional FEM has difficulty in remeshing. Using coupling-matrix-free iterative s-version FEM, a mesh of the whole analysis domain and a mesh in the vicinity of the hole can be created separately as a global mesh and a local mesh, respectively. In this study, we proposed a parametric analysis system to analyze the die with a hole for V-bending process, and we evaluated the results in terms of fracture mechanics.
