Hello,
We need to come up with a procedure for extraction of bearing-bypass load for joint analysis (currently metallic joints and thus focus is on fatigue related) from FE model. Typical FE representation of joints include a Spring/DOF 1D element for fastener and 2D shell representation of sheets. We want to start simple with riveted joints.
In our initial attempts, we were focusing on a 3 row riveted joints with single fasteners in each row. Further, we had included holes and rigid elements and we got good correlation with hand calc. Unfortunately, the above is turning out to be a little complicate and not so accurate when we expand the joints to multiple rows of fasteners with multiple fasteners in each row (currently we are at 3 x 3).
So seeking help on getting some reference materials which might provide us with an idea on how to proceed. My search on Google so far has yielded some material but none of them provide satisfactory guidelines.
I had created a similar thread in General FE forum, but this being an aircraft specific issue, thought it may get higher eyeballs in this section. Apologies for duplicate threads. I can delete the other thread if mods/Admin deems necessary.
