Due to high shear rates, this process is associated with the formation of adiabatic shear bands (ASB) in the blanking zone. For an in-depth analysis of the effects arising in this process and to support the prototyping of blanking tools, a numerical simulation is required. For this purpose, material parameters, which are valid at elevated strain rates are necessary. In this study, the parameter identification for the GISSMO damage model is presented. For the parameter identification, a series of coupled experimental and numerical investigations were carried out on 22MnB5 and EN AW-5754 with a sheet thickness of 2 mm. The main objective was to determine the damage and failure behaviour of the investigated materials under different loading modes (or triaxialities). The resulting data was used as input for the subsequent optimisation of the parameters in LS-DYNA and LS-OPT.enFE-SimulationDamage modelhigh-speedLS-DYNA620670ConferencePaperStanzenHochgeschwindigkeitsbearbeitungWerkstoffschädigungModellierungAluminiumlegierungMangan-Bor-StahlSimulation
