I agree about the tensile stress having less of a singularity if the connection was modeled as bolted. However, this area is in one portion of a pretty complicated structure.
I haven't spent much time in the way of sub-modeling so I was a bit hesitant to do that.
In reference to your...
Thank you ESP, corus, and rb1957 for the replies.
I wanted to post a picture of the basic area of interest I'm dealing with. Hopefully this will better explain what I'm after.
The blue plates (both sides) are welded to each other, same for the red plates. However, the connection between the...
Additional info: elements are bricks with midside nodes turned on, using Autodesk Simulation 2012

I've searched eng-tips.com and also have spent quite a bit of time googling my issue, but for now, I'm not having any luck.
The attached pictures best explain the issue I'm dealing with. I'm sure it's stress singularity in the model as I've refined the mesh the stress increases in same...
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...
