Abstract

The paper presents the procedure for calculating stress in gas pressure tanks using finite shell elements for linear and geometrically nonlinear analysis. Therefore, a procedure has been developed to automatically generate the necessary data for the finite element method (FEM), such as geometry, numbering of elements and nodes, and the determination of forces. Forces are calculated from: pressure difference in relation to external pressure; hydrostatic pressure and gas pressure; and pressure vessel weight. It enables fairly simple and easy use of developed software in everyday practice and provides great opportunities for further upgrading and fundamental determination of the impact on parameters for different types of tanks and pressure containers in general.

Keywords: finite element method (FEM), deformation, cylindrical shell, gas pressure
