Abstract:
An axisymmetric analysis was developed to investigate the tearing phenomenon in cylindrical Hydroforming Deep Drawing (HDD). By theoretical and finite element simulation methods, the critical fluid pressures which result rupture in the workpiece were studied. The results showed that the theoretical pressure path is an upper limit of the tearing path. The effects of anisotropy, drawing ratio, sheet thickness and strain hardening exponent on tearing diagram were also investigated. It is shown that die profile radius is effective on blank profile radius.
