Pre-tension
Pre-tension
(OP)
I'm modelling a bolted flange and have to pre-load the bolts.
In the past I used temperature dependent properties in order to obtain an specific pre-tension force.
But I've read something in the help about specific pretension elements. Are they easy to use or would it be wise to stick with the temperature?
Has somebody any expierence or advice.
Thanks

RE: Pre-tension
I hoped it would save me a few iterations, so that's great.
Only one question remains for me, what causes the need for iterations.
Why does the bolt-force change when the temp method is used, is it because the deformed shape of the bolt changes the shrinkage. Or are their other influences.
