That’s actually one of the things the study is going to look at, I plan to model some geometrically perfect cylinders on ANSYS and see what it churns out, compare with theoretical calculations in order to verify ANSYS isn’t handing me nonsense, and then I plan to carry out a buckling analysis on...

That third one looks to be a god send, no idea why it never came up when I searched for it. Thank you very much!

Hi Prex, Believe me, I have googled every combination of “Buckling” “Cylinder” and “Externally Pressurised”. I would not have came here to ask for the forums help if I had not exhausted all other means. If you google “buckling of circular cylinders” all that is returned are papers discussing...

Sorry, I wasn’t clear in my original post. I’m looking for an equation that finds the critical buckling pressure of a radially loaded cylinder. For example, the computer model is telling me that my cylinder will buckle when the external pressure is 106MPa, in order to verify the simulation is...

Hello, I’m currently carrying out an FEA study looking at the elastic-plastic buckling of externally pressurised cylinders (loaded radially). In order to verify my analysis, I’d like to compare with analytical equations, however I am struggling to find equations for a cylinder pressurised...

Hello, I am currently carrying out an FEA study using ANSYS of a cylindrical pressure vessel with an ellipsoidal head, in order to verify the results produced by ANSYS I want to do the hand calcs, however can not find equations for the max principal stress of an internally pressurised...
