Esteemed experts,
does Caesar II require to confirm inplane and outplane sif directions (as you have to do for a branch connection) when you define sif on bend?
Thanks in advance.
Best regards

yes. When user input sif values, must define branch connection type then only C-II understand this is branch.

if user not define branch type then C-II calculates stresses as pipe connection not branch.

Note that pipe connection and branch connections inplane and outplane are different.

so user must define branch type in any one location.

Yes, for branches you have to confirm sif directions.
What about for:

-1. A simple bend?

-2. A bend with dummy leg?

I supposed to take bend sif from FEBend and input them as is in Caesar (FEBend inplane in Caesar inplane and FEBend outplane in Caesar outplane) for both the above.

Instead, for the dummy leg, I supposed to take from FEBend the highest value between inplane and outplane sif for dummy leg and put this value in Caesar inplane and outplane sif for dummy leg.

Any comment is appreciate.
Thanks.
Best regards

what code are you using? if you're using B31.1 for example, you can only have one SIF. so yeah, I'd choose the highest one.

If you model the dummy pipe directly to the bend node, then CAESAR will already know which way is inplane, which way is outplane since there are 3 elements attached to the node.

If your modeling methodology involves adding one rigid element connecting the bend node to the dummy pipe, then CAESAR doesn't know which way is in plane and which way is outplane. You may either use the highest SIF to be conservative, or you may have to model another rigid element to "trick" CAESAR into correctly determining the inplane and outplane directions. To make your life easier if you use this dummy modeling technique, just use the highest SIF unless you find it to be too conservative.
