Reply To: creep analysis_ benchmark the data

[John Doyle]

If I understand your statement, you "have inputs like time dependent creep strain values, deflection and constant stress and temperature".  Did you use this data to curve fit time hardening creep?  If not, then I would recommend you follow curve fitting procedures documented in Section 6.4 of MAPDL reference Guide.  6.4. Creep Material Curve-Fitting (ansys.com)

If you have already curve fitted a creep model and you are trying to validate what you have, I would recommend going back to the source of your original input and try to reproduce (for comparison and validation) the same experiment that generated the input.
