STRESS ANALYSIS OF PRESSURE VESSEL WITH DIFFERENT END CONNECTIONS

ABSTRACT A thin cylindrical pressure vessel has been analyzed for different end connections using analytical and finite element analysis. The main objective of project is to compare stress distribution in the pressure vessel for different end connections viz. hemispherical, flat circular, standard ellipsoidal and dished shape. The various dimensions of pressure vessel like internal diameter, thickness of vessel and end connections has been decided using analytical design and three dimensional model is prepared in modeling software Pro-E and analyzed using FE tool ANSYS. The analysis has been carried out for 2-D axysymmetric analysis, 3-D horizontal pressure vessel with saddle support and vertical pressure vessel over the stand.
