Ogden model

Hi,

I am wondering what is this "Kb" parameter in Ogden constitutive equation for rubbers? Please take a look at this picture, I am talking about those three parameters in the table. I could figure out what are Mu and Alfa, but what what is Kb?

Thanks a lot for your help.

RE: Ogden model

According to the head of our engineering unit

µ = shear modulus in MPa
α = an exponent and is dimensionless
Kb = bulk modulus in MPa
