Sažetak
The main objective of this paper is numerical analyses of cylindrical pressure vessel with changeable head geometry (semi-elliptical and hemispherical heads) and comparison of results in means of precision and time needed for getting the solution. Manufacture technology of pressure vessel cylinders and heads are described, and construction geometry of various pressure vessel heads is presented. Discretisation style of finite element models, boundary conditions, and results are detailed shown and explained. Based on analytical solutions for membrane stress state of pressure vessel, numerical analysis of it is performed also. Comparison of harvested numerical results for above mentioned pressure vessels are shown tabular, with values of time needed for getting the solution too. And comparison of analytical and numerical results for pressure vessel with hemispherical heads is shown too.
