Another way to tackle this in case we fail in this code requirement is to run an Elastic plastic analysis considering the strain hardening effects and large deformation effect. If the solution converge, then the force-moment equilibrium is achieved. But this type of analysis is quite tedious. The only question for this high plastic strains will be how many cycles we can safely cycle it. A simplified elastic fatigue analysis considering plasticity correction factors Ke is available in ASME. I don't know if a more detailed elastic plastic cyclic stress analysis can be done. I haven't gone so far in that field of study.

Any other opinion is highly appreciated. Corrections are welcome.
