Towards an accurate springback prediction : experiments and modeling [PDF]
, 2018 Finite element (FE) simulations are used extensively during the tool design stage to predict the springback; it can then be compensated for by adapting the tool’s geometry. The tool is adapted in such a way that the formed product takes the intended shape after springback.

Prediction of Springback in Long Channels [PDF]
Acta Metallurgica Sinica (English Letters), 2015 Sheet metal forming is one of the most preferred manufacturing processes in automotive and aerospace industries. However, due to increase in fuel prices and more stringent environmental regulation, these industries are facing many challenges to meet the criteria. Due to this, many efforts in design and manufacturing were considered and presented. Those
