Numerical study of textures and Lankford values for FCC polycrystals by use of a modified Taylor model

A modified Taylor model is presented which statistically considers grain interaction in a polycrystalline aggregate in terms of a standard deviation for the symmetric part of the velocity gradient. The model can be solved using a Newton iteration method. We simulate crystallographic rolling textures and the anisotropy arising from uniaxial tension tests (Lankford values for different directions in the rolling sheet plane). The results reveal in part a good agreement with experimental data. (C) 2003 Elsevier B.V. All rights reserved.
