Experimental and Numerical Investigation of the Effect of Anisotropy on Springback in U-Bending Process
In this research, the effect of anisotropy on springback in CK67 steel sheet in U-bending process was studied by finite element simulation and experimental approach. The finite element software, ABAQUS/EXPLICIT 6.7, was used for simulation. In order to verify the simulation results some experiments were performed. The obtained results indicated that increasing the bending angle to the rolling direction resulted in an increase in springback. The results of the experiments were compared with simulation results. There was significant agreement between simulation and experiment.
