Objective: This Paper investigates to determine the stress distribution and failure location for a given pressure vessel using Finite Element Analysis (FEA). Comparing the FEA results with analytical results shows that the FEA software predicted the failure location very well for the symmetric shaped pressure vessel. By modifying the design and keeping the same material of the given pressure vessel, we could reduce the induced stress in the pressure vessel or we can increase the working pressure. The results are to be compared on the basis of Maximum distortion energy theory also known as Von Mises-Hencky theory i.e. Von Mises yield criterion. And the deviation between the analytical results and the software result, around the critical location to be checked for the stress discontinuity. Since it is an axis-symmetric pressure vessel, it is allowed to be modelled as a 2D axis-symmetric model and analysis is done.
