Bulge test dimensioning

The bulge test parts must be made. The idea for this is that a nitrogen tank will supply nitrogen at incremental pressures to a thin foil until it bulges and breaks. In order for this to work, a fixture is needed to hold the foil in place and apply pressure.

One aspect of this test includes o-rings. Page 109 of this reference gives me some baseline to go off of for my o-ring groove dimensions. I'll be using a 2 mm thick o-ring, just because it looks like a good size.
