I've read through the DNV-RP-C203 code (Fatigue Design of Offshore Steel Structures) and I feel that I have a grasp on the hot-spot method described in there, however, I'm inquiring as to the best way to determine stresses for fatigue in locations that have a full penetration weld.
Does the extrapolation method described in the DNV still work? Because it's a full penetration weld I hadn't planned on modeling any welds as the plates being welded are perpendicular to each other (basically it's 4 plates welded together that form a ring, I've attached an image that hopefully helps) and was unsure whether I could extrapolate to the to weld.
Any help is appreciated.
