My name is Bash Phd  in colorado school of mines and I am newbie in soil modeling  and I just started my PhD study  months ago. I am experimentally and numerically studying the stress distribution undernath the padfoot roller at the first stage, I need to have a constitutive model for soil with both dilatancy and hardening behaviors.

 I read about some models as Advanced Mohr-Coulomb or Modified Mohr-Coulomb which exit on some commercial software as PLAXIS, DIANA, ABAQUS... However my final goal will be the coupled dynamics-consolidation problem related topadfoot roller  load test therefore I wish to have a source code of one model and then developed it further.

If any one of you knows about any open-source code for such a constitutive model (Advanced Mohr-Coloumb for soil with both dilatancy and hardening behaviors) or any other advise can help me about this, could you please tell me how/where I can find it?

Thank you so much for your help and your time,

Best regards,

Bash
