Research on Algorithm of Springback in Sheet Metal Forming

Article Preview

Abstract:

The springback is one of the phenomena in sheet metal forming. It is very important for bending dies and sheet metal part to predict springback amount. In this study, according to different material models and different methods, the formulas of the radius of curvature in the neutral layer and springback angle after loading removing are given based on the principle of sheet metal bending. The results from the formulas of the radius of curvature in the neutral layer and springback angle, and experiments are compared. It is analyzed that the factors influence on springback and accuracy of the formulas. The results show that it is little difference for different formulas. The results from the formulas of the radius of curvature in the neutral layer and springback angle after loading removing close to the experiments.
