Hello All, 

I am trying to mimic my experimental results with a model in ANSYS, and incorporate creep. 

The experiment is simply measuring deflection of this old timber over the course of a few weeks in order to try to find a few material properties. 

However, how do I find the constants purely from the data below?

Any help would be massively appreciated. 

Thank you in Advance!

I assume by "Norton-Bailey"  you mean an expression of the following form:  

In Ansys, you can curve fit the Time Hardening Creep expression, with C4 set to zero. 

You would have to convert your displacment values to an equivalent strain (=delta_L/L).

Please refer to Chapters 4 and 6 of the MAPDL Material Reference Manual or more details.

Dear Joshua Davies,

I saw your post about the calculating the creep constants from the experimental data. Have you found the solution for this? while now I too have the same problem, I could not find the right solution.

Could you please help me with that?

Iam looking forward for your response.

Kind regards

Chandra
