In order to minimize the space of bent tubular parts, a bending technology with small bending radii is requested. Tube shear bending is a suitable technology to realize a considerable small bending radius, which is very difficult to be manufactured with common cold-bending methods. It can be applied as an effective means when space limitation is a main design factor. Utilizing the shear bending process, production of compact and unified elbow tubular parts is feasible. In this paper, the procedure of tube shear bending has been introduced. Also, an elasto-plastic 3D simulation analysis for shear bending process of circular tubes was undertaken. As the result, the deformation behavior of tube as well as the effect of pushing force have been clarified.
