Analysis of tube hydroforming in a square cross-sectional die

A mathematical model considering sliding friction between the tube and die is proposed to explore the plastic deformation behavior of the tubes during a hydraulic expansion process in a square cross-sectional die. This model is used to predict the forming pressure needed to hydroform a circular tube...
