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

steel research international, Volume 94, Issue 7, July 2023., 2023 This concerns stress–strain relationships for plain carbon steels used in pipelines, obtained either by tensile testing (with or without hoop direction flattening) or by profilometry‐based indentation plastometry (PIP). PIP is applied nondestructively to outside surfaces.

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

Springback prediction of magnesium alloy sheet with nonlinear combined hardening
工程科学学报, 2017 Springback is regarded as one of the main defects that occur in sheet-metal forming processes. Therefore, improving its prediction accuracy, especially under highly nonlinear conditions, is important for researchers. In this paper, constitutive equations

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.
