Design of the virtual model of re-drawing process

Résumé

This paper deals with the develop the finite element modelization of the re-drawing process in order to create his virtual model. The finite element is a method that permits to reduce the time and the cost in the designing. Then in a second time a good finite element model permit to avoid or complement laboratory characterization of material for re drawing. methodology for developing a laboratory inverse re-drawing device. The drawing process is performed in two phases: a direct drawing of a circular blank followed by a second reverse redrawing
phase on the same device.
A work is also done on the finite element model for the single deep drawing. This single deep drawing is used to validate the parameters of the numerical model. The main goal of this simulation is to define geometrical parameters of the process, in order to design a reverse re-drawing machine, and have the possibility in the future to compare experimental results and finite element results. The second goal is the estimation of the blank reaction (ability to support the process), and eliminate as well the default obtain during the simulation.
