To reduce CO2 emissions, increasingly higher-strength packaging steels are being developed which allow the use of thinner sheet thicknesses. At the same time, this is accompanied by increasing complexity in the product and process design. To reduce cost-intensive trial-and-error processes, numerical\nsimulations offer potential at this point. The representation of the material behaviour in the simulation requires the description of a flow curve as well as the anisotropic plastic material behaviour in the form of yield locus models.\nDue to the characteristics of higher strength packaging steels with high temper rolling degrees and strong ageing phenomena, the determination of the relevant characteristic values has not been possible so far. Therefore, this work deals with the development of a strategy to characterize packaging steels\nfor the fe-simulation. The hardening description was done by optimizing the tensile test, as well as the use of hydraulic bulge tests. The description of the anisotropic plastic material behaviour focused mainly on the r-value\ndetermination by inverse modelling, in addition to the description of the first yield locus quadrant by bulge tests. The presented methods were used to parametrize material models for three different packaging steels. Based on relevant forming processes a suitable validation procedure was derived, in which the quality of the simulation could be shown in comparison to the state of the art.<\/p>","protected":false},"excerpt":{"rendered":"
