Abstract

A modified Taylor model is proposed for quantitative evaluation of the formability parameter of sheets of metals and alloys - the normal anisotropy coefficient (NAC). The model takes into account the contribution of the crystallographic texture and structural anisotropy of the material under study. The model was used to predict the dependence of the NAC on the angle between the rolling and tension directions in the plane of the Al-Mg-Si alloy sheet. Good agreement was obtained between modeled and experimental values of the NAC.
