Numerical Simulation of the Hydroforming Process 2000-01-3305

Hydroforming is a metal forming process that uses in addition to the usual forming tools, water under pressure. This method has several advantages, such as: high precision and elimination of some common defects of traditional forming processes (non uniform thickness and local buckling). This work presents numerical simulations of the hydroforming process, using the finite element code for large deformation problems METAFOR [1,2,3] (METAl FORming). To perform the analysis, a full non-linear algorithm is used and contact between bodies is taken into account. A 3-D CAD-type graphic environment has been developed for modeling the tools.
