Hi all. This is my first post, so go easy on me if I violate any forum protocols. I have a simple Section VIII Div.1 pressure vessel that will operate in cyclic service. I would like to perform a Fatigue Analysis as per the rules of Div.2, AD-160 Fatigue Evaluation, Appendix 4 Stress Analysis, and Appendix 5 Fatigue Analysis. I have refered to Appendix G Examples of Formulas and Rules and feel somewhat comfortable analyizing the shell. However, I am drawing a complete blank with finding proper formulas and methods to analyze the heads, nozzles, and thermal conditions. Can anyone offer perhaps a set of "sample" calculations that I could mimic, or offer some guidance as to where to find the proper forumlas? Any and all input will be greatly appreciated, I look forward to your responses.
