Hello
In the B31.3J, general note 7(e) says : The flexibility and stress intensification factors apply only if the following conditions are satisfied: (e) - the matching run pipe thickness, T, and diameter, D, are maintained for at least two run pipe diameters on each side of the branch centerline
I've tried it on Caesar, and it seems that it still calculate the SIF, even in this configuration which should abide to the 7(e) rules :
The left part of the run pipe is smaller than two run pipe diameters. However Caesar still gives me a SIF, so am i not understanding correctly the rule or is Caesar forgetting this note?
Also, if flexbility and stress intensification factors doesn't apply, does that mean that a flexibility model cannot be made (and that a more detailled FEA needs to be made?)?
Thanks in advance
