Hi,
ANSYS offers two types of
large deformation viscoelasticity models - large deformation, small
strain (Visco-hypoelasticity) and large deformation, large strain.
I
am using plane182 element which supports viscoelasticity, large strain
and large deformation. When I use the 'nlgeom, on' flag in my analysis,
which of the above two viscoelasticity model is being used?
How do I specify to use Visco-hypoelasticity or large strain formulation
for my analysis?
Thanks,
