Anyone working in this area? Abaqus doesn't have soil model which
including anisotropic hardening. I am interested in the one proposed
by Dafalias in 1987. I feel someone has done this job. Anyone has
any information about this?
Thanks.

don't use this gentleman's model, he's churned out a lot papers and none
seems having drawn much attention from within academic circle.
in general, there are two methods to model anisotropic harding:
one based on yielding surface theory and the other no.
from my personal point of veiw, those without yielding surface look
more promising, like modified Osgood-Ramberg model. this is because
for geomaterial, yielding is hard to define, on the other hand, even if
yield can be defined, a lot multi-ax

i am interested in this subject too. could you tell more about the "modified
Osgood-Ramberg model", cause i can't find any stuff from Google about it.
I only know about the yielding one.
