Material models for highly dynamic metal forming processes

Abstract

Nowadays, industrial processes like sheet metal bending or punching are performed with high precision. Further optimizations are only possible by simulation and appropriate material models and parameters. Goal of this work is to find a material model suitable for both, bending and punching processes, including the effects of plasticity at high strains and strain rates. The models are calibrated by material tests like tension or torsion tests.
