I'm curious about how one would go about estimating the internal pressure in a compliant balloon.

I am assuming that I would need the following:

1. Stress-strain curve of the material

2. Diameter of the uninflated balloon

3. Thickness of the uninflated balloon

4. Final size of the inflated balloon

5. Assume that the balloon is spherical and expands so

How would I use this data to help me get a reliable estimation?

Thanks in advance!
