For purposes of this review, springback is the elastically driven change of shape of a metal
sheet during unloading and following forming. Scientific advances related to this topic have …

Complex (nonlinear) unloading behavior following plastic straining has been reported as a
significant challenge to accurate springback prediction. More fundamentally, the nature of …

The prediction of springback in sheet metal is vital to ensure economical metal forming. The
latest nonlinear recovery in finite element analysis is used to achieve accurate results, but …

A new two-step electromagnetic forming (two-step EMF) which combines electromagnetic
forming (EM forming) with electromagnetic calibration (EM calibration), is proposed for local …

To describe the nonlinear stress-strain response in the unloading-reloading process, a
model was proposed for the variation of the elastic modulus during the process. This model …

Bent parts of complex shapes with high precision are increasingly required. To achieve a
high precision of parts, especially the required bending angle, a suitable design of process …

Materials modeling and numerical formulations were conducted to describe the complex
material behavior upon strain path change in order to enhance the prediction accuracy of …

Springback is one of the most important problems that should be compensated in sheet
metal forming process with the increasing application of advanced high strength steels and …

In this paper, a novel approach is proposed to measure the Bauschinger effect, transient
behavior and permanent softening of metallic sheet subjected to reverse loading. The …

Springback prediction is necessary when applying high-strength steel sheets to automotive
parts. The accuracy of springback prediction depends on the material model, which …
