Numerical analysis of necking in stretch-bending based on modified maximum force criteria
(IOP Conference Series: Materials Science and Engineering, 2021)
The necking criteria based on the maximum force principle, such as the Swift and Hill necking models, have been extensively used in the past to study sheet formability. Many extensions or modifications of these criteria ...

Numerical analysis of flanging using tailored rubber pad forming on AA7075-O sheets
(Material Research Forum LLC, 2024)
The flanging of metal sheets is extensively used in the automotive and aeronautical industries to provide rigidity or support for subsequent assembly. Flanging by rubber pad forming is one of the most common processes for ...

Formability analysis of incrementally hole-flanged parts using different tool sizes
(Material Research Forum LLC, 2024)
This contribution analyses the formability of incrementally hole flanged parts using different tool radii (10, 20 and 47.9 mm). The smallest radius (10 mm) can induce full incremental benefits in the hole-flanged specimen, ...
