What is Predicting Springback in Metal Stamping about?

The document describes an analytical method for predicting springback in metal sheets after double-curvature forming operations. The method models the sheet as a shell of revolution divided into segments, with constant strain assumed within each segment. An energy approach is used to determine the strain distribution by minimizing total strain energy. The model accounts for bending effects and bending/unbending effects. The method is shown to accurately predict strain distribution and springback in axis
