If you have experimental test data, measuring the rate dependent material response, you can generate the creep coefficients via curve fitting. Please refer to Chapter 6 of the MAPDL Material Reference Guide for details.  For creep, in particular, please refer to Section 6.4 for procedures and guidance.  Also, refer to the MAPDL Commands Manual for  'TBFT,,,,' for syntax details.
