On many occasions during my Inventor Stress and Inventor Nastran training courses I have been asked ‘Can we use bolted connections already created in Inventor?’
My answer has always been unfortunately NO. Inventor Nastran uses the classical method by representing the bolt with a beam element. However, setting up bolted connections within Inventor Nastran relies on selecting faces that are in contact with the bolt head and nut. Meaning the need to split faces within Inventor and this process is very time-consuming. This normally in extreme cases yields to just using the bonded contact between the plates normally held by bolts.
