Improvement of the scoring process for easy open ends : from the industrial issue to simple shear tests
Amélioration du procédé d'incision des couvercles à ouverture facile : de la problématique industrielle à l'essai de cisaillement simple
The improvement of the openability of easy open ends leads to a reduction in residual thicknesses under the scores. This reduction has to be made while maintaining the integrity of the material. The present study in aimed at understanding how this can be achieved. The study investigates the mechanism of material deformation and damaging during the scoring process of different aluminium alloys in order to identify the conditions for safe downgauging beyond the currently used thicknesses. The simple shear tests technique has been used to correlate ductility to deformation behaviour. Anisotropy of ductility has been related to shear banding and this is one of the aspects studied here.
