Bolted connection with a slot




I want to model a slotted connection with FEMAP.

I have two plates, modeled as shell elements, one plate has holes and the other plate has slots.

They connected with a bolt and a nut. The slots on one of the plates are for different thermal expansion between the two plates.


Until now i used the "hole to hole" connections using only holes(no slots) and released a rotation for thermal expansion, but this is not what i am after.


The bolts also have pretension and the friction between the two plates needed to be taken into account.


What will be the best way to model this? Anyone did this before?


Appreciate any input.
