Abstract

We propose a modified Taylor model for quantitative evaluation of the normal anisotropy coefficient (NAC). The model takes into account the texture and grain shape contribution of the material under study. The model was used to predict the dependence of the NAC on the angle between the rolling and strain directions in the plane of Al-Mg-Si alloy sheets. There is good agreement between the calculated and experimental NAC values  of 6016 aluminum alloy sheets. The good agreement was achieved by taking into account the texture heterogeneity through the sheet thickness and the elongation of grains in the longitudinal and transverse directions.
