Find Yield displacement and Yield strength of steel under cyclic load

TL;DR Summary: I have experimented metal bars under cyclic load, you can find the picture attached of the hysteresis loops of "Load vs displacement" of the experimental work... 13 steps (each step 3 cycles)
Now I want to find the point where the steel started yielding and the yield strength so I can calculate dissipated energy and stiffness and also the damping ratio.
If you have an idea, please help, I may provide more details if needed.
Appreciate your help.

Welcome to PF.

Is this for schoolwork? Can you show your work so far please? Thanks.

Yes, it's
that's the work, you want me to share the data from the experiment. or What do you mean?

I'll go ahead and move it to the schoolwork forums for you then.

No, it's your schoolwork, so you must show your work. We cannot help you until you show your work on your schoolwork problem/project.
