Hi,
Can anyone suggest good resources for learning everything about buckling collapse analysis of thick walled cylinders under external pressures?
Thanks,
Mike

I've been searching the NASA documents, but have come across only one useful paper on the buckling collapse of a cylinder. Is there any other database other than the NASA Technical Reports Server to look for NASA documents?
Thanks,
Mike

But none of the papers deal with buckling of thick walled cylinders. I cannot come across any text that explains buckling due to instability in thick cylinders.
I am trying to find the buckling modes due to external pressure in FEA. In order to do so, I need to apply an initial deflection or initial load. How do I calculate this load?

Right now I just need to find the collapse pressure, and the buckling mode. I can find the collapse pressure using FEA and hand calculations, but I am lost on how to find the buckling modes of collapse.

The ASME code gives me formulaes to calculate buckling but does not explain the theory of collapse instability in thick walled cylinders.
desertfox,
The link in your post does not work?
Thanks,

I tried the link and it works for me, you have to give it a minute or so to download.

I guess I don't understand what you are trying to figure out. You either have elastic (Euler buckling), plastic collapse (yielding), or something in the grey area in between.
If I look back at your 3 Mar 09 13:39 post, if you follow the analysis procedure in Article 5.4, you will find your answer.
The reason that there are different design margins in Division2 for the different analysis procedures is that each analysis procedure is unique and has strengths and weaknesses for estimating the buckling collapse load.
