They ar é used in oiI, space, chemical, nucIear power and mány other industries. High pressure gas bottles, propellant ta nk, s mall auxiliary tank, s torage tank, solid propellant motorcase, and pressurized c abins are the type of pressure vessels w ith internal pressu re mainly us ed in aerospace industry. Cylindrical and spherical shapes are usually employe d in a pressure vessel. Though spherical pressure ve ssel requires thi nner walls than t he equivalent cylinder f or a given pressure and diameter, they ar e v ery complicated and e xpensive t o f abricate. He nce cy lindrical pressure ve ssels are pref erred ove r spherical press ure vesse ls. Pressure vessels uséd in aerospace structurés are rotationally symmétric shells subj écted to internal préssure.

Due to geo metric discontinuity i.e. Minimization of the discontinuity stresses at the junction of the cy linder to e nd connections is t he most c ritical issue.
