On the Use of Maximum Force Criteria to Predict Localised Necking in Metal Sheets under Stretch-Bending
(MDPI, 2017-11-02)
The maximum force criteria and their derivatives, the Swift and Hill criteria, have been extensively used in the past to study sheet formability. Many extensions or modifications of these criteria have been proposed to ...

Recent Approaches for the Determination of Forming Limits by Necking and Fracture in Sheet Metal Forming
(Elsevier, 2015)
Forming limit diagrams (FLD’s) are used to evaluate the workability of metal sheets. FLD’s provide the failure locus at which plastic instability occurs and localized necking develops (commonly designated as the forming ...
