Dear Group members,

I want to calculate the Norton creep constants from the experimental data.

Can anyone tell/suggest to me what are the methods available to get Norton Creep Constants from the experimental data?

And also how many parameters(like stress, strain and temperature) do we need to know to calculate the constants?

 

Thanks in advance!

Kind regards

Chandra

Hello Chandra Sekhar Narra,
Bailey-Norton Creep Law or the Classical Power Law for Creep states the creep strain rate has a dependency on Temperature in K, A material constant defining a creep-temperature relation, the current time, the total uniaxial stress for the respective time, and the constants. This law represents primary and secondary creep in a single formula.

Please find the following discussions and references which may seem helpful in addressing the concerns.
Chapter 4: Nonlinear Material Properties (ansys.com)
Chapter 6: Material Curve-Fitting (ansys.com)
How to find Norton-Bailey Creep Constants? (ansys.com)

Hope this helps!

Thanks,

Sahil
