Abstract
The influence of alternating bending loads as they occur during roller levelling on the mechanical properties of sheet metals is not yet fully understood. A detailed knowledge of the influence of the commonly used levelling process on the resulting properties of sheet material is needed in particular for the design of subsequent processes with narrow process windows. To investigate the mechanical property changes during loading conditions similar to roller levelling, sheet samples of mild steel DC01, α-titanium and pure copper (CU-DHP) were subjected to alternating bending loads with different amplitudes for up to 9.5 bending cycles. An isotropic hardening behavior according to a Voce description could be shown for the DC01 deep drawing steel with a strong dependence on the load amplitude applied per cycle. A strengthening behavior that depends on the loading amplitude could be observed for α-titanium as well. In contrast, pure copper featured minor changes with a tendency to soften. For all three materials, changes in springback were present after one bending cycle.
