Fatigue Evaluation in nozzle to head junction

Fatigue Evaluation in nozzle to head junction

(OP)
Good morning colleagues,
I did a rough fatigue evaluation vs.pressure cycles following Div.2 criteria. For stresses determination used the Stress Index Method. But I´m not convinced of my results.
Is anyone familiar with this subject whom I can explained what I did and see whether I was right or not?
Thanks in advance

Send me details of your geometry, materials and the expected loading conditions and I'll take a look at it for you.
