Hi,
I am using Creo 2.0, and I am interested in finding out more about the stress in a joint due to a prestressed bolt. I am using a dummy-model, consisting of two identical plates(aluminum) with 18mm holes in the middle. I am using the fastener feature and prestress my M16 bolt(steel) with 59.8kN. I use fixed separation=on and default bonded interface(no contact interfaces defined whatsoever). After the first run, Fastener1_axial_force=24kN, as I understand for the second run I must prestress 59.8*59.8/24=149kN, is this correct?
Furthermore, the stress in the joint is high, there are considerable regions where it is above 200MPa. As most aluminums have an Rp0.2 lower than this, this is a problem.
So the question is: Am I missing something? Is the Creo fastener tool a good tool to see the stresses induced in the joint?
Best
