Hi There,

I read the troubleshooting documents. My model is force control repeated loading system. It means I know the upper and lower load limits of my beam. I tried to apply force load case with external force monitoring points, but it did not work. How can I apply force instead of prescribed deformation and monitor the reaction forces?

Dear Sir,
Thank you very much for your reply, I managed to monitor the load.
Could you please explain the meaning of unloading factor in CC3DNLC2?

I already read that. Could you explain bit more about it?

Dear Sir,

Thank you very much for your reply.

I'm trying to validate results of a reinforced concrete beam, subjected to repeated loading. In my experiment, I applied repeated loading in three stages, before concrete cracking, elastic plastic range and closer to ultimate limit.
When I tried to model this, the only changing factor in the concrete material model (which I used for static loading) is the unloading factor. I set the factor as zero and tried to validate my results.
In first stage, there weren't any displacement change for all cycles, In second stage peak displacement showed less displacement change and valley displacements changed considerably. I think unloading factor has affected to this behaviour.
My questions are
                       1. Does unloading factor effect considerably for these issues?
                       2. If yes, how does it effect and how can I find a proper value?
