Forming limit curves for quasi-static and dynamic working-media-based forming processes [PDF]

open access: yes, 2018
The production of complex, multi-functional, high-strength components is becoming increasingly important in the sheet metal industry. Especially with small batch sizes, quasi-static working-media-based forming processes (WMF), such as hydromechanical ...

Understanding Size Effects and Forming Limits in the Micro-Stamping of Industrial Stainless Steel Foils

open access: yesMetals, 2020
This study investigates the effect of grain size and composition on the material properties and forming limits of commercially supplied stainless steel foil for bipolar plate manufacture via tensile, stretch forming and micro-stamping trials. It is shown

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]

open access: yes, 2009
In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

Ultrasonic-Assisted Incremental Microforming of Thin Shell Pyramids of Metallic Foil

open access: yesMicromachines, 2017
Single point incremental forming is used for rapid prototyping of sheet metal parts. This forming technology was applied to the fabrication of thin shell micropyramids of aluminum, stainless steel, and titanium foils.

Exceeding the Forming Limit Curve with Deep Drawing Followed by Electromagnetic Calibration [PDF]

open access: yes, 2012
We show that the materials quasi-static forming limit curve (FLC) can be exceeded by the process chain composed of deep drawing followed by electromagnetic forming. We form circular cups as close as possible to the FLC by deep drawing.

Effect of initial state on formability of AA1060 alloy under quasi-static and electromagnetic forming

open access: yesJournal of Materials Research and Technology, 2022
It has been reported that the forming limit of materials can be improved during electromagnetic forming (EMF). However, the detailed mechanism of this phenomenon remains unclear.

Cusp forms as p-adic limits [PDF]

open access: yesJournal of Number Theory, 2022
Ahlgren and Samart relate three cusp forms with complex multiplication to certain weakly holomorphic modular forms using $p$-adic bounds related to their Fourier coefficients. In these three examples, their result strengthens a theorem of Guerzhoy, Kent, and Ono which pairs certain CM forms with weakly holomorphic modular forms via $p$-adic limits ...
