Dear all,
I am trying to use Abaqus to modeling undrained cyclic triaxial test for liquefiable soil. I am wondering how could I applied the cyclic load. I should apply it by amplitude or I should the loading sequence in soil constitutive model? If anyone knows familiar with that, please help me.
Thanks,
Shile

Dear Shile,
for element tests, it is better to use a Matlab script rather than Abaqus, which would be much slower. The cyclic loading can be applied by either amplitude deviatoric stress or amplitude axial strain.
Best regards
Dear Shile,
I suggest you to use software like: Incremental Driver or Triax elemnet test Driver. Those element test softwares are much more convenient for you to modeling undrained cyclic loading traixal tests.
You can find them in this website.
Regards
I am also trying to figure out how exactly can anyone apply cyclic loading in Abaqus. I apply amplitude/time data for the same but my deviatoric stress isn’t reaching the negative side. Can anyone tell me how to apply stress-controlled cyclic load in Abaqus?. e:g qmax(max deviatoric stress is +-300.
