Design and Analysis of Puncture Disc Pressure Vessel

This paper investigates using finite-element analysis (FEA) to determine the stress distribution
and failure location for given pressure vessel. 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 changing 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 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 from the software result around the critical location has been checked for the
stress discontinuity. Since it is the axis-symmetric pressure vessel, it is allowed to be modeled as
a 2D axisymmetric model and analysis is done.
