Résumé

A yield function which is able to represent the anisotropy of aluminium sheets is proposed. It is based on the definition of an effective stress from two modified deviators. The modified deviators are obtained from the stress tensor by two linear application that carry the anisotropy. This yield function has been implemented in a finite element code. It can be used to represent the anisotropy of a 2024 aluminium thin sheet
