Abstract

In tube expansion process, the tube is axially forced onto a die having a certain cone angle to increase its diameter. In this study, the effects of the die angle, the coefficient of friction between the tube and the die surfaces, the tube thickness on the energy absorption, and the external force to be applied are examined for the tube expansion process. The numerical results obtained by using Abaqus FEA software are compared with the analytical results. It is observed that the absorbed energy and the axial force results predicted via numerical simulations and calculated through analytical formulations are generally in good agreement.
