Creep -Creep constant-creep simulation


      Hii all,

               I am working on a creep analysis,I have constants which is posted in ansys forum,but I need constants which is derived direcly from thr model or research paper.creep constants include various models like garofalo,time hardening,strain hardening,mod.strain hardening,Gen.time hardening,Norton method,etc.And constants like C1,C2,C3,C4,etc.So people who ever is interested please reply.And If you have those papers dealing with creep constant please share with and help us to move forward.

      Thank you.

      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.
