How to calculate thickness of thin sheel for radial buckling?
How to calculate thickness of thin sheel for radial buckling?
(OP)
Hi Guys,
i got a situation where a thin shell (open ended) of 1300 mm dia X 950 mm length is subjected to a uniform external pressure on outer cicumference say, 1500 KPA ....
How can i calculate the safe thickness of the shell for buckling ??
The material of the sheel is steel.
Thanks in advance.

The Roark formulas and ASME assume the shell is stiffened at the ends. If one end is actually free, no stiffeners at all, I know of no solution. This is a situation that occurs in storage tanks.
The different tank codes also include provision for wind loading on cylinders, which is essentially an external pressure problem, and also include requirements for the top stiffener.
Be careful using the Roark formulas, as they give the buckling pressure, not the allowable pressure. And that buckling pressure is not necessarily a minimum buckling pressure, either.

I looked at 4th edition ...and its on page 690, chapter 14, Elastic Stability.
Thanks for your help guys ...
