factor of concentration of tensions(sif) by non-planetary component

[SonOfEther]

Hello
I hope I am not off-topic (or off forum)
Would someone know how to concoct me on a source where they can find concentration factors of efforts to be used in a small study of fracture mechanics on a component that cannot be traced back to a plate? (which is typically seen the reliable results obtained for that geometry).
a drawing of the piece is attached. this is connected by prof. channeled to a tree to which it transmits a couple receiving through the radial pins that you see.
Thank you.

finite element analysis! around you find various texts with factors of concentration of the planned efforts, but I believe that all the theoretical studies you find refer to plane models. if you want to get something more adherent to the linear theoretical model is just the fem analysis.
