It was concluded that when the end connections of pressure vessel changes, the s tress concentration zo ne are c hanged for the same pressure.

Pressure Vessel Design Project Software To EstimateNon-linear axisymmetric FEA considering both geometric and material non-linearity have been performed in ANSYS software to estimate the stress in dome and cylindrical shell of pressure vessel. Based on the analysis, optimum thickness which meets the strength requirement of the material is arrived at.

Index Terms - axi-sym metry, domes, Finite element analy sis, non-linear analy sis, Pressure ves sel 1) I NTRODUCTION Pressure ve ssels are vessels c ontaining, which are sub jected to external o r internal pressure substantially different from the ambient pressure. They ar e used in oil, space, chemical, nuclear power and many 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 used in aerospace structures are rotationally symmetric shells subj ected to internal pressure. The pressure vessel design fo r a given pressure is prim arily based o n diameter and thickness of the cylinder portion. The cylindrical portion of the pressure vessel configurations will be stressed maximum u nder inte rnal pressure and go verns the design. 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. Cy lindrical s hell w ith circu mferential mismatch w as analy sed using FEA so ftware AN SYS a nd stress magnification factor was co mpared with published literature3. Work related to analysis of pressure ve ssel with different end connections are reported in4-10.
