Dear Sirs,
i want to know how to calculate in steps and example, how to calculate manually the deviation of shell out of roundness when external pressure according to UG.80 is applied?

UG-80 is pretty clear. Perhaps you could be more specific where you are having trouble, or perhaps show us your calcs so far.
