Theoretical prediction of forming limit strain of sheet metal is developed in the framework of the three-dimensional general bifurcation theory. The onset of the three-dimensional discontinuous velocity "eld in the biaxially stretched uniform sheet is predicted. Three fundamental mode vectors, i.e.
In order to develop a three dimensional finite element computer program related to the sheet metal forming process modeling for car industry, we are currently implementing an adapted finite elastoplastic strain module. Our aim is then to progress in representing the deep drawing steel behaviour, es
