All structural analysts know that finite element analysis (FEA) results can only be as accurate as the underlying assumptions within the model itself. However, modeling discrete fasteners with solid elements, contact, and bolt preload can add significant complexity to otherwise linear models and quickly becomes computationally prohibitive.
This webinar will consider the best practices associated with simplified fastener representations, with a focus on approximations using rigid and beam or spring elements, which still provide realistic stiffness representations and can even allow for robust strength assessment of each bolted joint. After introducing the best practices, the webinar will showcase how to implement these approaches with a live Femap demonstration.

Oh, that freudian slip at 28:30 is spot on.

Oooooof haha

Thanks for the great info. Rachael knows her stuff and presents it well. Cheers.

Hello, on minute ~33-35 you show an easy way of modeling RBE but the video is pretty poor quality.
can you maybe do that part again?
Thank you!

Great video! Thanks very much for sharing - would there be another upload of this video anywhere? There's a little choppiness in the video that made it hard to follow near the end. Cheers!

Hi Xavier, This is the best copy we have at the moment. There were some connection challenges/lags during the live event that were captured on the recording. Let us know if you have any questions!

I never had issues with using RBE2s for thermal models as long as Rigid=lagrange is on and the CTE is set. The hand calc does the rest.

you guys did a great job with this presentation. Are there any references so that I can read up more on the topic? Is there a recommended book or paper?

The video and audio are very out of sync...
