Computational simulation of an Erichsen test applied on a DC-06 steel sheet

ABSTRACT Nowadays, the use of computer simulation on forming processes as stamping and its variants, is an habitual development activity of big industries, and also it is slowly being introduced in SME (Small and Mediumsize Enterprise). One of the main advantages of it is application lies-in the reduction of costs regarding new projects, products and processes developments. Likewise, these tools are widely used to reproduce complex physical phenomena. During the deep drawing process, the material is mechanically stressed, therefore requires knowledge of it is properties, such as ductility, mechanical strength and plasticity. Thus, characterization tests like the Erichsen test are performed to recreate a controlled deep drawing process. In this paper, using the Simufact.Forming software, a deep drawing test was simulated, for a steel sheet DC06 IF-base, of nominal thickness 0.7mm. During the simulation is taken into account the conditions of lubrication, pressure of blank holder, dimensions of the dies and friction coefficient. At the same time, the experimental test was also performed in order to compare and validate the simulated results.
