摘要

In this study, the finite element method was used to investigate the cold elliptic-shaped flaring process of metal tubes with a conical punch from a tube billet. A series of simulations on tube flaring was carried out using the FEM program DEFORM 3D. The influence of process parameters such as tube wall thickness, punch conical length, aspect ratio of elliptic shape, friction factor, punch fillet radius and strength coefficient of the billet material on the critical flaring ratio of the tube were analyzed.
