CELAS3 vs RBE3
CELAS3 vs RBE3
(OP)
I'm modeling a fastener in FEM, which of the following should be used? DOF spring or RBE3. My understanding is, RBE3 gives a more realistic results. Please share this knowledge and if you have any reference, that would be great too. Thanks.





RE: CELAS3 vs RBE3
I recommend performing some tests, or at least getting access to some test data, then try modeling it both ways. You'll come up with a defendable position that way. This question has been circulating around Nastran (and other) user discussions for years, but I'm always convinced by analytical correlation to test data.

SWComposites: I'm new in using Femap and Nastran for modeling and getting result. Thus, I'm modeling a simple model by connecting two plate elements using nodes.
Thanks
