Ratcheting and Fatigue analysis with kinematic hardening model

Hi,

I'm looking for a way to perform a structural analysis to obtain the stabilized response of a structure subjected to periodic loading (thermomechanical loads), the material involved is exhibits kinematic hardening and it can't be modeled with a stabilized stress-strain curve so I need to capture the stabilized response (plastic shakedown) and then perform the damage calculation.

In Abaqus there is the Direct Cyclic analysis (link below) which is perfect for that type of analysis

https://abaqus-docs.mit.edu/2017/English/SIMACAEANLRefMap/simaanl-c-directcyclicfatigue.htm

I'm wondering if there is a way to implement it in Optistruct though the TSTEP- Fourier card.

thanks

Simone
