A Methodology for Springback Prediction 2001-01-3409

The springback of simple geometries can be predicted through theoretical analysis, however problems arise when transferring this analysis to the manufacturing environment. To determine why this is the case, a study of small curvature free bending through theoretical analysis, manufacturing data and Finite Element (FE) simulation was completed.
The theoretical analysis provided an understanding of the behavior of springback and gave accurate predictions in a controlled environment. The manufacturing and Finite Element data verified the trends predicted by theory, but lacked in accuracy.
The paper concludes by proposing a prediction method based solely on the geometry that is well defined in both environments.
