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.

Accurate prediction of springback after coining operation
Journal of Physics: Conference Series, 2018 A common approach used to reduce springback in flanging operations is to apply additional coining around the bent regions. In this strategy, the sheet metal part is compressed between two rigid dies having a clearance less than the sheet thickness. The aim is to bring additional compressive stresses especially around bending dominated regions.

Prediction of springback in multi-point forming
Cogent Engineering, 2017 Flexible forming techniques, such as multi-point forming (MPF), are employed in manufacturing to reduce the time and cost of production. MPF uses a set of height-adjustable pins to construct free-form three-dimensional surfaces. Springback is a common phenomenon in forming including MPF which, if not properly catered for, will lead to parts that are ...

Denoising Diffusion Model With Pixel‐Adaptive Convolutions for Sheet Metal Forming Analysis
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Traditional tool development processes in mechanical forming, especially for pressing tools, are often limited by time‐consuming trial‐and‐error cycles, which rely heavily on expert knowledge. These cycles can create bottlenecks and increase costs.

Evaluation of constitutive models for springback prediction in U-draw/bending of DP and TRIP steel sheets [PDF]
, 2011 U-draw/bending experiments and simulations were performed to investigate the characteristics of springback in sheet metals. The finite element method is frequently used for the simulation of springback, but the predictions are strongly influenced by the ...

High‐Velocity Ballistic Impact Performance of FFF Printed PEEK With Different Infill Patterns
Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.This study examines 3D printed PEEK under Izod, quasi‐static, and high‐velocity impact. Hexagonal infill shows the highest Izod impact strength and superior quasi‐static energy absorption. However, under ballistic impact, all patterns behave similarly, indicating performance depends on infill at low velocity, but on intrinsic material properties at ...
