Hi All,
can someone please advise how to model a typical Victaulic coupling in Caesar? I looked through the Caesar's application manual but there was no mention of Victaulic coupling. Can a Victaulic coupling be modeled similar to a tied expansion joint?

Your assistance would be much appreciated.

Thanks

Flexo,

Annex an example.

There are a number of earlier posts in this forum discussing Victaulic Couplings (they can be found using the [Search] feature.

You can also find a suggested modeling procedure in one of our earlier newsletters, here.

Thanks HAG and Richard for the information.

Hello,

I was searching and studying many possible approaches for an accurate modeling of the flexible victaulic coupling in CaesarII; I Found the way addressed by Coade engineering news and that of the attached do not consider thrust pressure, as well, this method when used while modeling too many flexible couplings in the system usually yields to un-convergence.

My question here, i tried to model the flexible victaulic coupling as per mentioned in AutoPipe forum which model the flexible coupling exactly as tie rod expansion joints with zero length and zero stiffness. the modeling will be exactly as follows.
say segment node 10-20 to be connected with segment 40-50 with flex. coupl.

then:

20-30: Rigid (half weight & Length of the victaulic)
30-35: expansion joint zero length & zero stiffness (Thrust pressure can be applied)
35-40: Rigid (half weight & Length of the victaulic)
20-41: Rigid Zero WT with Victaulic length (Cnode 40), Rest's: (X, RY, RZ with gaps; Y,Z,RX)

Please Rich. Correct me if i am wrong in that mentioned approach.

Rigid coupling can be simply model as sif 2.3 connection, and check allow bend, and displacement
