Flatness defects after bridle rolls: a numerical analysis of leveling
Source abstract
Abstract
Leveling is a forming process used in the aluminum industry in order to correct flatness defects and minimize residual stresses in strips thanks to bending under tension. This paper introduces a 3D finite element model to simulate the sheet threading in an elementary part of a leveler called bridle rolls. It can compute plastic strains and residual stresses through width and thickness, but predict the deformed strip after springback and potential buckling phenomena as well. The influence of geometric and mechanical parameters (like friction or rolls profile) on final flatness are also investigated. Finally initial defects are taken into account and the model shows how they are modified.
