Optikai elven történő alakváltozás mérése az akadémiai és az ipari gyakorlatban

With the rapid development of the automotive industry, the demand for new and improved materials has changed dramatically. The industry has set many expectations for these raw materials, one of the most significant of which is the reduction of the weight of the materials used. This is of great economic and environmental importance, as by reducing the total weight, emissions can be reduced. However, it is important that the original strength properties of the material are maintained and, where possible, improved. This article defines a high strength material (DP 600) forming limit diagram and its use in a finite element (AutoForm R7) software environment. The study presents how finite element software results can be refined by defining the material map of the material used for modeling.
