Simulation of tubes hydroforming

Résumé

Tube Hydroforming is an advanced technology used on a large scale to obtain complex parts for different applications. The paper presents the results of hydroformed T tube simulations, using FEM, in order to study the influence of radius of hydroforming die corner, cycle time and internal pressure toward the hydroformability. The axial feeding of punches remains constant and it was used to increase the tube formability. The analyses provided information about
hydroformability considering the tube deformation, thickness and stress variations for the deformation conditions conducted.
