And those wonderful units for some of the older members of NZ!

The program isn't ready for public release, although the spherical shell module works fine.  Before I release it, I'll add in the archaic units for the benefit of those in Myanmar, Liberia and the United States.

Yes, I used .8 as the usage factor for a516-70.  Until you know what the minimum thickness of a formed head is the numbers have to be considered approximate anyway.  For example, .75 inch HY-100 will clearly get Scott where he wants to go, but I don't know if that would require 1 inch plate or 1.25 inch plate to ensure a minimum thickness of .75 inch after forming.

I like your program Sean.  Looks like there's a bug in it though...everything displayed in metric.  :)  Where do I make a "feature" request for english unit output?

FYI:  This is for a 72" sphere with 1.25" thick material.  Where this may differ from Jon's calculation is that the Usage Factor, eta, used in this program is 0.67 as specified by ABS.  Jon apparently used 0.8, which increases conservatism.
