I’m trying to learn creep analysis in Ansys, and am currently working on deriving creep constants, specifically C1, C2, and C3 for the Norton Power Law.

I understand that the equation is usually shown in 2 ways:

epsdot = A * (sigma^n) * (t^m)

or

epsdot = A * (sigma^n) * exp(-Q/RT)

Which form does Ansys use? I can’t seem to find an answer in any of the manuals or anywhere online.

For example, I know solid works uses the first form, where C1 is A, C2 is n, and C3 is m.

Thanks

I understand that the equation is usually shown in 2 ways:

$$\dot\epsilon = A \sigma^n t^m$$

or

$$\dot\epsilon = A \sigma^n \exp\left(-\dfrac{Q}{RT}\right)$$
