The analysis is carried out for a cylindrical vessel with a nozzle subjected to external loading consisting of longitudinal and circumferential moments and radial force. The Flügge-Conrad solutions with the Sanders-Simmonds concentrated force solution are utilized for a local analysis, to which asymptotic approximations for the effect of the vessel length and continuity around the vessel circumference are added. This is incorporated in a computer code FAST for which set up and run times are minimal for a given case of geometry and load. The comparison with experimental results is about as good as can be expected for eight models, with parameters in the ranges: 50 ≤ D /T ≤ 2530, 0.01 ≤ d /D ≤ 0.5, and 6.5 ≤ d /t ≤ 240. Hence, the calculation should be useful for an improvement in nozzle design. Example curves and tables of stress factors are included.
