Alex,

I posted this a few months ago.
This might help? It's a simple vessel calculator. Input Young's Modulus
and Poisson's ratio for the material.

Use the site Roger referenced to get the values:

If you don't have MsOffice you can download a free XLS viewer from:

I have another vessel calculator somewhere, I have to look for it.
When I come across it I will post it.
