Abstract

In this paper a review on simulations using FEM for sheet metal hydroforming is
presented. Hydroforming can be done either with a punch and a pressurized fluid
that replaces the die or by using fluid under pressure instead of the punch and with
a die. The main types of sheet hydroforming techniques are: with fluid, either
directly or with a rubber diaphragm; or with rubber, that can behave like a fluid
under a high enough pressure. There are different variations of hydroforming, using
different types of fluids with different properties. Some of these hydroforming
methods have been simulated by different researchers, using different FEM
software, like Dynaform, Abaqus, etc. The purpose of these FEM simulations is to
obtain results that are close to the results obtained experimentally, to be able to
compare them, which can be quite difficult, because of the fact that there are
multiple parameters that can influence the results.
