Abstract Pressure vessels are a commonly used device in marine engineering. Chemical, petroleum, military industries as well as in nuclear power plants. Until recently the primary analysis method had been hand calculations and empirical curves. New software advances have made finite element analysis ( FEA) a practical tool in the study of pressure vessels, especially in determining stresses in local areas such as penetrations, contact surfaces for compound cylinder and other areas difficult to analyze by hand. This project set out explore applicable methods using theoretical analysis and finite element analysis in pressure vessel analysis. A comparison between the analytical and numerical solution is presented, and it is found a good agreement between them. Having tested three dimensional, symmetric and axi-symmetric models, the preliminary conclusion is that finite element analysis is an extremely powerful tool when employed correctly. Depending on the desired solutions, there are different methods that offer faster run times and less error. The two recommended methods included symmetric models using shell elements and three dimensional models using elements. |
