Stress Analysis of Pressure Vessel With Different Type of End Connections-A Review

Pressure Vessel is a closed container designed to hold gases or liquids at a high pressure, higher than atmospheric pressure. Due to operating conditions, high stresses are developed in Pressure vessel which results in cracking and bursting of vessel. Pressure vessel is subjected to high internal pressures as mathematically it is very difficult to solve such a complex problem. Various research papers presents analysis of pressure vessel with dished heads to resist internal pressure, analysis of vessel with different configuration of saddle support with stiffener ring and reduction of stresses. Lot of work had been carried out to develop various numerical and experimental methods to study stresses in pressure vessel. Analytical and experimental techniques have some limitations such as cost associated with multiple prototypes and experimental iterations. Therefore, Finite Element Analysis is most viable tool for design and analysis of pressure vessel with American Society of Mechanical Engineers standards. In this paper we are working on approximate stresses that exist in cylindrical pressure vessels supported on two saddles support are calculated under the different type of end connections by using Finite Element tool. Static structural analysis is done in order to calculate stresses in vessel. The thickness of vessel heads are varied with the composite material till the maximum von-moises stress is within the limits.
