The principal factors influencing strength of cylindrical thin
shells are geometry, boundary conditions, out of circularity and
material yielding conditions. Imperfection is significant under axial
loading. Boundary conditions play the major role compared to axial
loading when subjected to external pressure. Stiffener also raises
strength to a certain degree.
The purpose of this research is probing the above-mentioned phenomenon
by finite element method, and compare numerical analysis with code and
classical thin shell theory. Checking results of examples by both method,
it''s known that finite element analysis can estimate precisely ultimate
strength of cylindrical thin shell.
