simulate the extension of rubber

[dominic.gamelin]

Is it possible to simulate the extension of an air spring bag when compressing it?

if yes, can you let me know if there is a representative video?

You can "fake it" for show and tell purposes.. You can't "accurately" simulate it using Inventor alone. You would need Nastran or other non-linear capable solvers.. Inventor FEA does linear materials only. 

Example of faking it..
