Press forming simulations: Is our characterization hitting the mark?

Abstract. The accuracy of press forming simulations relies on the quality of the characterization experiments used to determine material parameters. For reliable predictions, the characterization conditions, such as deformations and rates, must represent those encountered during forming. In this study, a forming simulation of a partial dome geometry was analyzed, extracting over 3 million data points to compare deformations and rates with conditions typically used for material characterization. While the findings are specific to the simulated geometry, they highlight opportunities to improve characterization methodologies. Key recommendations include focusing in-plane shear characterization on smaller angles and lower shear rates, extending bending characterization to larger curvatures and higher rates to capture wrinkle formation, and focusing ply-ply slippage measurements on small slip distances and low pressures.
