bolted flange
bolted flange
(OP)
hi all,
I am doing fe analysis of bolted flange analysis. I have modeled this with solid elements only one segment.
I want to know the how to give the boundary conditions for this assembly.
Please help.

RE: bolted flange
i'd start modelling the fasteners by connecting the two sides with an x-, y-, z- constraint. you can contraint the two nodes together, or insert (zero length) springs between them. fancier would be to include the contact area around the bolts (where the faces are clamped together.

RE: bolted flange
I think that your model shoul include the whole bolt ( that is, a slice that double yours , model the bolt hole and, unless you're interested in the bolt, model it as rigid, or as a bar w/ suitable properties.
As boundary conditios, I'd use peripheral continuity in the faces of the slice, and fix the end of the pipe - provided it's far enough.
