Controlling Springback With Compensation Strategies [PDF]
, 2004 Several measures are applied in order to reduce springback but it is not always possible to reduce springback sufficiently. Therefore techniques have been developed to counter springback by modification of the tool shape (overbending).

Effect Of Die’s Shape, Sheet Thickness and Type of Alloy on the Springback Phenomenon [PDF]
Engineering and Technology Journal, 2012 In this paper the effect of the springback on the bending operation of different materials and alloys have been studied. Dies were designed and constructed in different shape ( U-die , V-die) for several sheet’s thickness.

The springback penalty for robust signal recovery
Applied and Computational Harmonic Analysis, 2022 We propose a new penalty, the springback penalty, for constructing models to recover an unknown signal from incomplete and inaccurate measurements. Mathematically, the springback penalty is a weakly convex function. It bears various theoretical and computational advantages of both the benchmark convex $\ell_1$ penalty and many of its non-convex ...

Finite element simulation of twist forming process to study twist springback pattern
MATEC Web of Conferences, 2017 Springback is one of the most common defects found in the metal forming of automotive parts. There are three conditions which can be considered as springback i.e. flange angle change, sidewall curl and twist springback and among them, twist springback is

Theoretical Analysis on the Bending Springback of Flattened Oil and Gas Pipelines
Chemical Engineering Transactions, 2018 Oil and gas pipeline leakage incidents occur from time to time, causing environmental pollution, property damages and other serious consequences. Flattening the oil and gas pipelines to stop the flow can effectively reduce losses.
