Modelling Bolted joint

[swapnil1511]

Hello all,

I am new user of Abaqus CAE and im trying to analyse an automotive differential casing mounted on a flange.

I needed advice on how do go about defining the bolting of dif case to flange as I only have the holes on both parts and not the actual bolt model.

Is using a kinematic coupling appropriate or should I use Tie constraint.
Currently I am selecting the nodes on circumference of adjacent hole and tieing them together. but not sure if its right or not.

It is kind of urrnt as I am on a deadline.

Thanks a

Two couplings and a connector or beam in between element is a common method to model simplified bolts.
