Simulating inflatables with Kangaroo

Hello,

I am using Kangaroo and Grasshopper to simulate inflating two plastic sheets that are sealed along edges and along internal lines. I have managed to achieve this in grasshopper, but I am wanting to be able to use it to see how this would work with actual pressure in kPa and actual material values i.e. Youngs modulus. Would it be possible to get any information about how these relate to the strength values for the two components.

Thankyou for any help.

My question as well!
