Tutorial for Bolt Modeling in ANSYS: Method 1
In this Video, bolt modeling using line elements is explained. There are at least 5-6 other methods where you can model the bolts differently. This method is generally used for global analysis. By global analysis, I mean that all the components of the assembly are modeled and analyzed using a single analysis. This method is a conservative approach where large safety margins are common. Pretension is not included in this method.
