during the triaxial test I should maintain the same lateral stress value
during the analysis, while the axial stress is increasing. The fact is that
from my simulation actually I see from the results that the lateral stress is
not kept constant, but it is increasing. How can I fix it? Am I wrong
somewhere?
One possible cause : lateral boxes have this maximum velocity. If the
axial velocity is too high, lateral boundaries cannot move fast enough
to adjust the stress. You need to increase max_vel or decrease strain rate.
Does it fix the problem?
