Constitutive law for linear elastic isotropic material in large deformation

I was not able to identify the constitutive law used for solid linear elastic isotropic material when the large deformation option is selected.
Is it the Kirchhoff-St. Venant law: Sx=(lambda)trE I + 2(mu)E
where Sx is the Piola-Kirchhoff II stress tensor, E is the Green strain, I the identity tensor and lambda and mu the Lamé constants?
Thanks.

Hi
I beleive the best reply is in the doc is like here:
page 7 SMEUG.pdf V3.5a as well as p165 and on, 173 and on
note some limitation with viscuoelastic material model
check also the smeref.pdf "large deformations" for the different application modes
good luck
