Result interpretation from Bolt - connectors

[lucmartzz]

Hello everyone,

I'm exploring some results from the use of bolt connectors. On the dropdown menu I see a lot of beam related plots but I would like to know more precise which one is the correct at the moment of do a correct interpretation. 

Thanks!!

Yeah, that's really confusing and not user-friendly at all...

Hi @lucmartzz 

Instead of trying to describe the dozens of results for beam elements listed on the page Autodesk Inventor Nastran 2022 Help | Beam Element Results Column Descriptions | Autodesk, can you clarify what result you are trying to find?

You may need to output the FORCE results so that you can look at the forces and moments in the element.

@John_Holtz thanks for getting back. Well, I just want to determine from the results if the bolts that I'm using are suitable for resist the shearing force or any results that can help with that. I did analytical calculation and compared with bolt generator calculations, unfortunately those are not matching, so I want to figure out with FEA if I can get more conclusive results.

Thanks in advance for your help

To get the shear force in beam, you want to output the FORCE results: "Analysis > Edit > Output Controls > Force". Then you will be able to view the result "Beam Diagram > Shear Force".

Also see these articles which have some details:

I did a tutorial, I hope it is useful for the community
