Abstract:
This report presents 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.
