Hey friends

I am modelling plasticity with isotropic hardening in abaqus. when I use mises plasticity, I have no problem and everything goes well, but when I switch to hill plasticity by adding the potential option from suboption in material properties edit section, the analysis starts plastcity from start of analysis and I do not have the elastic behavior before plasticity, ie plasticity starts in very low stresses and the material starts to yield at zero stress!!!

I dont know wheather I have missed sth in material properties or ..., I have good results when I delete the potential option
