Abstract

A numerical process control method developed in [1] is used in this paper to determine the deformations observed in tube hydroforming experiments. This method was incorporated in the finite element simulations to predict the pressure/end-feed histories to achieve maximum tube deformations without wrinkling. The analysis used deformation theory and Hill's criterion to describe the plastic flow, and forming limit data to predict the onset of rupture. The computed loading paths were applied in forming experiments using extruded aluminum 6061-T4 tubes that were hydroformed under free conditions and within a conical die. The resulting strains, deformations and loads to failure were measured for comparison with the model predictions.
