(The stress concentration factor can be obtained from peterson's stress concentration factor data hand book).
Solved! Go to Solution.
This is more up to you than from the NX NASTRAN solver side:
Then you see this is a job of the PREPROCESSOR you are running and the decision taken from the FEA user side of what element type to use to capture locally the stress field. If your mesh (both element type & density) is correct, then your stress results will mach perfectly with the stress concentration factor tables you have in the literature, sure!!.
