Predictions of Springback of Strain-Hardening Material in U-Shaped Bending Process

Abstract:

This study applies the finite element method (FEM) in conjunction with an abductive network to predict springback of different strain-hardening material in U-shaped bending process.Springback is investigated for different material parameters, such as strength coefficient of material, strain-hardening exponent and Young’s modulus, by finite element analysis during U-shaped bending process. The abductive network is then applied to synthesize the data sets obtained from the numerical simulations. Prediction results of the springback of different strain-hardening material in U-shaped bending process are consistent with the results obtained from FEM simulation quite well. After employing the predictive model can provide valuable references in prediction of the springback of U-shaped bending process under a suitable range of material parameters.
