摘要：

This paper presents a numerical methodology which aims to improve 3D thin sheet hydroforming processes. This methodology is based on elastoplastic constitutive equations accounting for non-linear anisotropic hardening. The experimental study is dedicated to the identification of material parameters from the global measure of sheet displacement, thickness evolution and internal pressure expansion. Applications are made to study the effect of die shape, anisotropic flow and hardening law on the hydro-formability of sheets.
