Do the rectangular plates have contact on the same face as the bolt load?

  • Care should be used when applying a Bolt Pretension boundary condition to a cylindrical face that has bonded contact. There is a possibility that if you apply a Bolt Pretension boundary condition to a cylinder that had a bonded contact region, the bonded contact will block the ability of the Bolt Pretension to deform properly.
