Can the large opening analysis method for pressure vessel shells be used for the stress calculation of openings reinforced with protruding nozzles? Is it safe or dangerous to calculate in this way?

The analysis method does not take internal expansion into account; therefore, if the calculation done by this method is sufficient, then the fitting with internal expansion will be even more than sufficient, which makes it a conservative approach.
