Hi Ashish,
Thanks for your replay. My issue Simply speaking, I'm doing nonlinear buckling analysis, so my results or the curve for the non-linear case are still linear. Even though I tried to reduce the yield strength and increase the scale factor, I'm still getting linear, and the stress should exceed the yield but not become less than before. I'm not sure what the problem is.
I will also attach some screenshots to make my question clear.
One more thing I want to do is use the arc length method. Is there any way to do it using ASYS 2023? What do you advise me to do? 
best regards

so the curve for non linear case should be like this 

but i got the curve like this
