Topic: creep problem for metals

Hi everyone!! I was glancing through the manual. I saw that creep formulation is only available for concrete models. Now I have very little info regarding concrete model, yet I am interested in modelling creep for metals and other solid material models. My question is this: Is OOFEM available for all kinds of creep analysis or only for concrete, If so can any kind of material creep be modelled using your concrete creep model?

Best Regards,
