Numerical simulation of deep-drawing process

In this paper, both rigid-plastic FEM simulation and experimental methods are used to systematically analyze axisymmetric deep-drawing process, summarize material flow law in deep-drawing process. The relation between punch force and drawing depth is measured with transducer and other equipment. Contrasting to the experimental result, it shows that this method is successfully applied to simulate deep-drawing process. The method of dealing with boundary conditions raised in this paper precisely simulate the material warping in the center and the cavity in the flange, and investigate the influence of friction and other parameters on the limit depth of deep-drawing. Although the program shown in this paper deals merely with the axisymmetric deep-drawing deformation, it could be applied to upsetting and forging process either.

Industrial integrated methodology for deep-drawing processes optimization by numerical simulation

Numerical Simulation of Deep-Drawing process strongly increased its performance in the past years: today several reliable research and commercial codes are available and have been well tested and run on most important hardware platforms, from workstations to supercomputers. Many applications have been developed dealing with not only academic or geometrically simplified problems but also large, complex industrial components; so next step in the future from an industrial point of view will be the integration of numerical simulation tools in processes and components design environment. The paper describes the main activities performed at CRF for achieving efficiency and dissemination of integrated methodology in order to optimize components, dies and processes. It also shows the results obtained in the numerical simulation of the deep-drawing process of a car component. The work has been done in co-design with CAD system suppliers, processes designers and numerical simulation experts. The code PAM-STAMP has been utilized in order to perform numerical simulations. The CAD-FEM integration and the role of numerical simulation in process optimization are particularly focused. Finally some experience concerning times, results analysis, impact of methodological procedures' performances and trends for the future are described from industrial point of view.
