Numerical Prediction and Reduction of Hat-Shaped Part Springback Made of Dual-Phase AHSS Steel
Metals, 2020 The springback in the sheet metal forming process refers to the change of shape after the load removal. It is usually undesirable, causing problems in the subsequent forming operations, in the assembly and negatively affects the quality of the final ...

Springback Coefficient Research of API X60 Pipe with Dent Defect
Energies, 2018 Dent is a common form of defect on oil and gas pipeline. Some dents will undergo elastic or plastic recovery due to changes in internal pressure, also known as springback.

Numerical Investigation of Springback in Mechanical Clinching Process
International Journal of Engineering Materials and Manufacture, 2017 In this work, a numerical investigation was conducted to study the springback phenomena in the mechanical clinching process. The springback values were calculated using finite element simulations and it was found that these values depend strongly on the ...

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

On the Springback of Explosive Forming
Transactions of the Japan Society of Mechanical Engineers, 1963 According to the many papers, explosive forming exhibits unusual features in as much that there is a relative absence of springback owing to the very high pressure of shockwave. The authors measured the springback of explosive bending of brass and aluminium sheets which were tried under the relatively low pressure of blackpowder explosion, ana found ...

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 ...
