RBE3 Weighting Factors

RBE3 Weighting Factors

RBE3 Weighting Factors

(OP)
Hi

Does anyone know how the weighting factors on an RBE3 element are calculated?
I know it has something to do with the distance between the node it is connecting but I cannot work out the maths behind it.
If anyone can help it would be appreciated!

Regards
Ian

RE: RBE3 Weighting Factors

Hi,
goto www.6dof.com and get yourself a user id. On the downloads page for Nastran there's a great article free to download that answers your question. It's called "The undocumented RBE3".
I do not want to post the article here as I don't know if its allowed.

Sorry,
the article can be found under Technical notes--> Nastran on the www.6dof.com page.
