Abstract
We introduce a simulation procedure for through-process texture and anisotropy
prediction, in particular for AA5182 sheet production from hot rolling through cold rolling and
annealing. The FEM package ‘T-Pack’ based on the software LARSTRAN served as a process
model. It was combined with physics based microstructure models for deformation texture (GIA),
work hardening (3IVM), nucleation texture (ReNuc), and recrystallization texture (StaRT). The
terminal sheet texture was used for a FEM simulation of cup drawing. A new concept of
interactively updated texture based yield locus predictions was employed. The simulation
predictions were compared to experimental data. The procedure can be applied to a wide variety of
Aluminum alloys.
