Reply To: Bolt pretension giving unusual results

All bodies changed to Structural Steel material.

Added a fixed support at cicular face of plate (Removed other fixed supports). 

Deformation is quite less. the bolt shank doesnt go on extending as it was happening earlier but the stress remains the same at the below circular surface area of second plate.

I doubt if this is a correct way(Fixing a inner circular surface of either one of plates - as this will not let the bolt apply compression on both the plates as one of the plates would get fixed).
