Input Material Data for Advance Computational Models for Forming Stainless Material

Original language description

During the last years there is a strong tendency of automotive industry to achieve suitable compromise between effort to lower environmental load at car operation by lowering its weight (thus to lower thickness of used parts) and on the other hand there is tendency to still increase the safety of passengers by utilization ultra-high strength materials. That is why these days are more and more important strength materials and alloys based e.g. on aluminium or magnesium. However industrial processing of these materials reveals quite a lot of problems. Thus these days there is a great demand for high-quality computational models within the numerical simulations for processing these materials because quite great portion of producing problems can be eliminated by pre-producing phase using numerical simulations (FEA). For precious numerical simulations computation is, beside geometry of part and tool, very important selection and accuracy of material input data subsequently regarding also selection of own computational model. During the last years there were developed a lot of computational models which within the metal forming regard yield criterions. One of these yield criterions is also anisotropic computational model named as Vegter model. The purpose of this paper is not only to describe such computational model but mainly to show procedure of measurement the most important input material data for stainless material to be computed by Vegter model. Such measurement is not only about static tensile test but there is used also the hydraulic bulge test to determine so-called bi-axial point in Vegter model.
