Dear all,
does anyone have the umat code for Hardening Soil or Hardening Soil-Small in Abaqus? For my current work I need a umat for Hardening Soil or Hardening Soil-Small in Abaqus. It would be highly appriciated if anyone can share me the code. Thanks a lot in advance!
Kind regrads,
Fuqin Yang

The theory of hardening soil model is not fully published, therefore it would be quite difficult to implement it in abaqus. If you try to implement it yourself, just a hint, the yield function for shear hardening in plaxis manual is only valid for pure triaxial stress path, which means for general stress path the yield function may not be applicable.
