On the Use of Maximum Force Criteria to Predict Localised Necking in Metal Sheets under Stretch-Bending

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 improve necking predictions under only stretching conditions. This work analyses...
