Springback Prediction of the TRIP Sheet Steel Stamping
Advanced Materials Research, 2011An enhanced elastic-plastic constitutive equation taking into account strain induced transformation is developed. The variation of the Young’s modulus with the martensitic transformation during stamping process is also introduced to improve the accuracy of springback simulation for TRIP steel.

Springback Prediction of Axial Symmetry Sheet Part Drawing
Advanced Materials Research, 2010Springback in drawing of an axial symmetry sheet metal part was studied. First of all, according to a springback formula of simple bending, the moment was modified by concerning of axial symmetry shape of part to construct a formula for predicting the springback. Then, springback process was analyzed with FE software Dynaform.

The Precise Prediction of Springback Based on GRNN
2010 International Conference on Artificial Intelligence and Computational Intelligence, 2010The deformation of sheet metal is so complicated that the prediction of springback will cost much time with FEM and the results may not match the facts. So it tried to build a function relationship between the springback and the craft parameters with artificial neural network (ANN) in this paper.

Improved prediction of springback on final formed components
Journal of Materials Processing Technology, 2004Abstract This paper investigates the major difficulty associated with the bending of sheet steel products, namely that of material elastic recovery (springback). Key material, and loading factors that influence springback have been assessed from an experimental study of this phenomenon, using a variety of forming methods.

Empirically derived equations for predicting springback in bending
Journal of Applied Metalworking, 1984(1) An empirical equation has been developed that predicts springback for a variety of die geometries on the basis of yield strength, thickness, and bend radius; and for some die conditions for bend angle, hold-down, plan view curvature, and punch-to-die clearance.

FEM prediction of springback control in air bending
2004Nei processi di piegatura libera della lamiera il risultato finale può essere influenzato in modo significativo dalle proprietà del materiale impiegato. In particolare, il ritorno elastico non è legato solo alle caratteristiche geometriche della lamiera piegata, bensì anche alle principali proprietà del materiale utilizzato (modulo di elasticità,
