Bolt thread stress concentration factors

[Aled87]

Dear all,
I'm attempting to determine stress concentration factors in screw threads for con rod bolts. I Have the nominal stresses defined but need to account for stress concentration due to notches.

I am unable to find any methods that account for notches in bolts so any advice would be appreciated, maybe simple FEA would be an option?

many thanks
