Hi Dave,
Thanks for the reply but I understand the differences between stress intensity and stress range. I have asked two specific questions which are clear and concise. could you please answer the specific questions on whether Caesar is performing the calculations correctly or not. I beleive Caesar is not complying with the approaches of ASME VIII Div 2 for fatigue assessment and not adding the calculated bending stress to the hoop stress before calculating the stress intensity even if the ASME VIII Div 2 still used stress intensities which it does not.

Please give direct answers to my two original questions to avoid ambiguity.

Regards
