Hello,
I'm working with the behavior law of Ogden. I have the terms (from tests...) which define the compressiblity of the material. Unfortunately the code I'm using needs the Poisson's ratio. How can I define the Poisson's ratio with the béta_i of the law?
I know that there is a formula ( Nu=béta/(1+2*béta) ) in the documentation of ABAQUS...but I don't know where it comes from...
Thank you.
