Chris,

I have been playing around with Roark and Young with the Mathcad Electronic Book that I have. Unfortunately the models are all in Imperial units. CH12 in R & Y at 12.7 gives some insight but continually cautions you on how large errors can occur.

I'll have a look at Nozzlepro and see if there is anything in that software.

Cheers

Geoff

This case is covered in Roark.. The conservative approach is to analyze it as a ring subject to dead weight supported at a point on the bottom. The equivalent shell problem is a lot more work--do it according to WRC 107 or the equivalent updated versions.
