Bolt Pretension Location

xxxxxxxx Member Posts: 1


It is always stated everywhere that Bolt Pretension must be applied to non-bonded-contacted surfaces, which makes sense since motion is not allowed for bonded contact and Bolt Pretension pulls two nodes into each other.

But consider a case that the screw is fully integrated into the thread. Entire surface of the bolt is on bonded contact and Bolt Pretension is not applicable. How should we model this situation.

Additionally, can you explain where and why Bolt Pretension occur on a shoulder bolt, on shank or threaded portion?
