PRESSURE VESSEL DESIGN BY FEA

This paper aims to Finite Element Analysis for the Pressure vessel design using ANSYSand ASME Code Book. The Pressure Vessel which is evaluated by manual calculations with Code book and on Ansys. The critical parameters of pressure vessel that are taken into account includes internal pressure, thickness, length, diameter and stress. The stress variation with respected to thickness is noted. A Mathematical relation (Regression Analysis) is developed for all cases. This equation refers to the stress value from ANSYS 14.5 APDL.If the ANSYS value is less than the allowable stress value, then the design is safe. Also, if the induced stress value is greater than code allowable value, then it can be taken as a factor while designing pressure vessel in ANSYS 14.5 APDL.
