Abstract

In order to reduce the trial-and-error practices, which are time-consuming and expensive, numerical methods for predicting the material formability and the hydroforming parameters are essential. This paper presents an inverse approach to tube hydroforming to efficiently predict the thickness, strain and pressure distributions for a given deformed configuration of aluminum AA6061-T4 tubes under free hydroforming conditions or hydroformed within a conical die. The analysis employed a membrane finite element formulation within the framework of the deformation theory,and Hill's criterion to describe the plastic flow. Hydroforming experiments of aluminum tubes using a conical die and under free conditions were also conducted, and the experimental results were compared with the numerical predictions.
