Hello, everyone
I have some questions about hardening factor. I got its description in Solidworks simulation help document.
- Hardening Factor defines the proportion of kinematic and isotropic hardening.
- For pure isotropic hardening, Hardening Factor has the value 0. The radius of the yield surface expands but its center remains fixed in deviatoric space.
- For pure kinematic hardening, Hardening Factor has the value 1. The radius of the yield surface remains constant while its center can move in deviatoric space.
I feel confused about this parameter, because I cannot find a similar factor in ANSYS. In ANSYS, it just uses two seperate models to discribe isotropic hardening and kinematic hardening, no partial isotropic hardening and partial kinematic hardening. So I doubt about the meaning of hardening factor for engineering application, do we need to make the simulaiton complicated?
Anyway, if I want to get hardening factor, what experiment should I do?
Thanks a lot.
it is a material property, have you considered asking the material provider?
I don't have specific experience in this realm but it looks like the testing is straight forward to load/unload and measure.

Before getting to this point, have you looked at both ends of the spectrum to see how much of an effect this actually has on your analysis? You could simply include the range and assumptions in your analysis report.
