    Status: Open => Answered

Bruno Chareyre proposed the following answer:
For CU, see #1 by Amiya.
For UU, again, there is nothing to do. Just as textbooks (should) tell you, conducting UU tests with different confining pressure is pointless because all tests are exactly the same from the solid phase point of view (i.e. in terms of effective stress). If you run one CU simulation with confining p=100, giving q_peak=300 , you can call it UU on a material pre-consolidated at 100.
You can then pretend this very same result q_peak=300 reflects the results of UU tests with p=200, 300  400,... since there is strictly no difference neither from theoretical nor computational points of view. I fail to see the point of such a trick, though.
Conducting UU tests with different confining pressure is pointless, that's it.
Bruno
