Summary:

The work presented in this paper utilizes advanced FE models of the pre-bending and hydroforming process to investigate the effect of bending boost and hydroforming end-feed on the hydroformability of a tube. A model of a rotary-draw tube bender was used to simulate pre-bending of DP600 tube after which models of hydroforming of the pre-bent tube were run with various levels of end-feed. By varying bending boost from low (LB), medium (MB) and high (HB), consistent trends in the strain and thickness distribution within the pre-bent tubes were observed. Three end-feed levels were simulated and showed that an increase in end-feed improved formability during hydroforming. The sensitivity of the models to bending boost was shown
