Fatigue Evaluation in nozzle to head junction

[juancito]

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
