interference betwen surfaces in a pretensioned bolt connection
interference betwen surfaces in a pretensioned bolt connection
(OP)
Hi all!
im modelling a bolted prestressed connection as showed in the image attached, is a 3d element model, and what u see is a section cut, in order to see the hole.
Im pretensioning the bolt with a temperature step, applied to the beam element section.(bolt central body)
the problem is that i get an interference between the bolt head and the compressed piece.
I know the problem is not in the temperature step because if I make a coupling betwen the beam element end (1) with the hole edge (6) it works nice.
*the interaction is surface to surface explicit
*the interaction property has normal behaviour with "hard contact", and tangential behaviour with "rough".
*the interaction property its the same than in the contact between compressed pieces (3), and there is working.
Has anybody an idea?
Thanks and sorry because of the language mistakes.

now the model does not behave like expected but thats another problem so i´ll close the thread.
thanks a lot Corus.
