One way to understand ( a bit ) nozzle loads is to read the corresponding chapter of
the book wriiten by: Bednar , i guess you will find this book in this site or some others !!!

The nozzle load work was started ( as far as I know ) by Bijlaard , based on thin shell theory. and he tried to convert the formulas into dimensless curves.

The whole has its limitation : nozzle and shell sizes , location of applied load ,..this is all covered by design parameters and trated in WRC 107.

If you are outside these boundaries then WRC 107 is not valid any..and you have to find other means for nozzle loads checking..for instance BS 5500 = PD 5500 appendix G ( but this has its limitations too ) or NOZZLE PRO of FE PIPE

what is thin shell theory?.Anybody can explain thin shell theory

[FATHI]

what is thin shell theory?.Anybody can explain thin shell theory

this is the Membrane Theory , you will end up globally with UNIT stresses in N/ mm or lb/ in , like = +/- (M/6*t) +/-( N/t)
in each direction , e.g. longitudinal and circumferential

This is explained in this BEDNAR book.
so get this publication, I believe it is in this forum

This is just to understand the theory and its limitations.

In practice, this is built up in graphs, hence the WRC 107 ,WRC 297 or PD500 appendix G.
Of course this is now implemented in various software for piping or vessels design.

Greetings to all , and ..good luck
