The estimation of the texture in a sheet metal induced by rolling is an important issue for the accurate description of forming operations as, e.g., deep drawing. In this paper, we discuss the influence of the number of grains in the polycrystal on the prediction of the pole figures as well as on the α and β fiber in the orientation distribution function. For this study, we use the Taylor model as homogenization method where it is assumed that the macroscopic deformation of the polycrystal is identically transferred to each single crystal.
