Abstract
The aim of this paper is to analyse the complex stress and deformation history during the multi-operation deep-drawing processes. A great ef fort is given to the choice of time integration scheme and contact pro blem because of the successive bending, unbending, extension, sometime s shearing, unloading, re-bending and so on. A numerical example for a cup multi-operation deep-drawing process shows the performance of the used numerical modelling.
