dc.description.abstract | 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 the maximum force principle under stretch-bending conditions and develops
two different approaches to predict necking. The first is a generalisation of classical maximum force
criteria to stretch-bending processes. The second approach is an extension of a previous work of
the authors based on critical distance concepts, suggesting that necking of the sheet is controlled
by the damage of a critical material volume located at the inner side of the sheet. An analytical
deformation model is proposed to characterise the stretch-bending process under plane-strain
conditions. Different parameters are considered, such as the thickness reduction, the gradient
of variables through the sheet thickness, the thickness stress and the anisotropy of the material.
The proposed necking models have been successfully applied to predict the failure in different
materials, such as steel, brass and aluminium | es |
