I see in a tool about the correction elasto-plastic using Neuber's rule, a limitation of the ultimate strength given by the Ramberg Osgood coefficient n.
Indeed the elastic high stress to rectify was corrected by the Neuber's rule using the stress-strain curve given by the Ramberg Osgood equation.
But the ultimate stress was corrected too with the stress-strain curve, assuming that the ultimate strain was equal to the inverse of n (Ramberg-Osgood coefficient).
Have you any idea where this assumption comes from? Method, reference...
Thank you,
Squall.
