Numerical Simulation of Dimensional Variations for Roller Hemming

Abstract:

A study to investigate the effect of hardening models on roller hemming in the case of aluminum alloy sheets is described in this approach. The most popular hardening models including isotropic hardening, kinematic hardening and combined hardening are studied using the uniaxial tension tests. Then the roll-in/out values over the hemline along width direction after pre-hemming with different hardening models are compared with the experimental results. It is verified that combined hardening model is most efficient to predict roll-in/out.
