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

EFFECT OF SPRINGBACK IN DP980 ADVANCED HIGH STRENGTH STEEL ON PRODUCT PRECISION IN BENDING PROCESS
Acta Metallurgica Slovaca, 2019 Springback is a common phenomenon in sheet metal forming, in which the material undergoes an elastic recovery as applied loads are removed. Springback causes the forming shape to deviate from the intended design geometry.

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.

Springback prediction and elasticity modulus variation
Procedia Manufacturing, 2019 Abstract Angular precision of air bending is directly related to the precision of the calculated punch stroke, which is computed in order to achieve the required sheet profile before the springback. The calculated springback accuracy depends on the elasticity modulus which, as it is well-known, decreases with increase of plastic prestrain. During the
