Bonded Contact for Fastener in FEA

Bonded Contact for Fastener in FEA

Bonded Contact for Fastener in FEA

(OP)
If I don't use rbe for predicting the load at fastener... What about using bonded contact?

Imagine in lap shear joint, I use bonded contact at the imprint area where it supposed to be bolt shank?

There was discussion in the team that this is quick and dirty way to check the joint strength but I'm not sure...

RE: Bonded Contact for Fastener in FEA

It's not friction that makes bolts work.

RE: Bonded Contact for Fastener in FEA

Oh, right Greg. I was thinking of the contact surfaces of the plates, but you're right about the contact surfaces of the threads. smile

RE: Bonded Contact for Fastener in FEA

modelling the joint as a bonded connection will give you the total load reacted, then presumably divide by the number of fasteners (assuming same fastener) for a fastener load … assuming load redistribution within the joint, which may be valid for ultimate loads, but would be invalid for fatigue loads.

Why not model the joint as common nodes. This'll still tell you the bulk load, and easier to implement ?

another day in paradise, or is paradise one day closer ?
