I am using SMART crack (Fatigue crack) in Ansys 19.2. So when I generate result for normal stress or von mises it focus on the crack front. Is it possible to obtain stress concentration value specifically at the hole region? Thanks in advance. I am sorry if my understanding is wrong, I'm just confused right now.

I would split the geometry a bit in order to get a square region around the hole of interest .

 

Then when looking at results you can select that square face (see below) that includes the hole and plot only stresses there.

Before this i alrdy tried to select surface element around the circle, but error popped up when i want to evaluate the result. Something on mesh changing error and the scope. i once saw a video on youtube on that. As you said, he select specific surface to evaluate and got the result. When i tried myself, error keep popping up.

No sure what you mean with surface element, but the idea is to select that face and look on the stresses only there (rather than entire body).

If you upload your model than we could have a look - also show what you mean with "selecting surface element" - do you mean a finite element (say plane stress elements) or a face?

There is an option for selecting element faces and others . I tried that but an error popped out. i already did it in different simulation to obtain the stress. Thank you for all your answer.
