Modelling of Pressure Vessels with different End Connections using Pro Mechanica

This paper deals with the Finite element modelling of Pressure vessels. Considering the fact that required thickness of hemispherical head for internal pressure loading is only half of that necessary for the cylindrical shell, authors have tried to develop a finite element model taking due consideration on welding involved at the end connections of cylinder to shell end in modelling using shell elements to model cylinder. Theoretical investigation and engineering applications shows some junctions are rational in structure, convenient in fabrication and less in cost. Thus some end connections are tested under FEA for the cause of resulting weight reduction of 30-35 %. The larger the shell in diameter the more the economic benefits it achieves. In this paper authors, describes its basic structure and the engineering finite element modelling for analysing, testing and validation of pressure vessels under high stress zones.
