Abstract: (6759 Views)
In this paper, the role of isotropic and kinematic hardening models are discussed in cold forming of a U-channel considering the springback phenomenon. The effect of influential parameters on the springback is also studied. For this purpose, a cold roll forming machine was built using a milling machine. The effects of forming angle’s changes, sheet material, roll geometry and sheet thickness are studied experimentally and numerically. The results show that the isotropic work hardening model is more precise in prediction of the springback. 304 stainless steel and AISI 1015 are used in experimental verification. Comparison of the simulation results with experimental values demonstrates the accuracy of the modeling.
