Hi guys,
Say we have a balloon, not completely inflated like in the sketch picture below.
I would like to come up with a set of equations connecting between the increase in pressure inside the balloon and the change in the following dimensions as a result:
1. "neck" length (shown as 40mm )
2. overall thickness (shown as 15mm)
3. balloon radius (shown as 100mm)
4. balloon material properties (young's modulus, yield strength, density if relevant)
So in theory I would be able to input the pressure inside the balloon and receive the "neck"'s new length (shortening) + new thickness + new radius as a result of the balloon inflating and 'taking' away from their dimensions
I would love someone to guide me and send me the right way.
I can't really use laplace's/pascal law because the thickness is not negligible.
Thanks a lot!
