I also wanted to mention that the data I used to create the input backbone curve is based on cyclic shear lab tests that were completed under the same vertical stress coressponding to the depth of overburden as the Vs/Vp measurements.

I was able to get the strain output in the worksheet (had to say 'yes' in the analysis settings 'output controls'). However it is unclear to me which strain & stress components I should plot for the shear stress vs. shear strain diagram (to compare with the MAT_079 input curve). E.g. what confuses me is that I do get results for EPTOXY, but EPELXY & EPPLXY both show zero. I have fixed the bottom nodes of the element, and applied a displacement in X-direction, holding both Y & Z direction constant.

Appreciate any help.
