Modeling of Bolts

ron.kunz
Dear all,
I have a big assembly and want to model bolts in the complete assembly. What is the best and accurate way to model this.
Cbar analysis is accurate enough to analyse the bolt forces. Boltstress is of secundair interest.
Are there examples for these bolts?
In addition bar orientation for this CBAR property, how can this best be modeled?
 
Thanks in advance

    Ron, there are many many ways to model bolts...the best "best and most accurate" way depends on the results you need. I have seen all of the methods describe above (and more) for modeling fasteners. For example, you mentioned bolt force - what about the moment? Also, how important is interaction of the bolt with the local structure? Another thing you didn't mention is the need to model a bolt preload. All of these influence the choice of best method.
