Edge to Surfaca Contact



Is there an option to define edge to surface contact for shell meshes (imagine a T like contact situation) ? You have this option for GLUE, but as I see NX Nastran does not offer such contact option.






Re: Edge to Surfaca Contact

You are correct in the context of edge-surface glue not having a general contact equivalent. Edge-edge contact exists, but that assumes that the 2D elements are very close to being in the same plane. There is a general surface-surface contact too, but that doesn't apply to your situation.


SOL 601 advanced non-linear does support node to surface contact. Don't take my word for it that it solves your problem, but I think it is worth reviewing the documentation and testing if it sounds promising. I believe you can set this up as surface to surface contact, but the source side is really reduced to nodes. Your edge elements would be the source in a surface to surface contact pair. Or maybe a better NX Nastran user can confirm that it can properly model shell edge to surface contact with its node to surface contact capabilities.

Thank you Mark, let me review and try this, then I will let you know the outcome.
