Affecting the Determination of Forming Limit Diagram for Sheet Metals
Tikrit Journal of Engineering Sciences, 2005 The sheet metal forming is defined as the ability of metal to deform plastically (stretch forming) without necking or fracture. To control the sheets forming operation failure a diagram is used , in which the ; accepted forming , failure and critical ...

Computational analysis of stress-based forming limit curves [PDF]
International Journal of Solids and Structures, 2007 AbstractThis article, through computational analyses, examines the validity of using the stress-based and extended stress-based forming limit curves to predict the onset of necking during proportional loading of sheet metal. To this end, a model material consisting of a homogeneous zone and a zone that has voids (material inhomogeneity) is proposed and

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

Influence of Temperature on the Forming Limits of High-Strength Low Alloy, and Dual-Phase Steels
Journal of Manufacturing and Materials Processing, 2023 High-strength steels (HSS) appear as a good alternative to common steels to reduce vehicle weight, thus reducing fuel consumption. Despite the excellent mechanical behavior towards its lower weight, its application in industry is still limited, as ...
