mooney-rivlin material data

[Me09]

guys, anyone has haperelastic (mooney-rivlin) material data for bone and muscle?

ok let me change my question, do you have any material data based on the mooney-rivlin method?

 

[vumat721]

Mooney-Rivlin is a hyperelastic material model. Experimental data is not based on it, but rather may be fit by a mooney-rivlin model.

Also, I'm not a bioengineer, but I doubt that mooney-rivlin is what you want to model bone.

thanks for the responds, as far as I know mooney-rivlin is a strain energy potential method of a haperelastic material. according to the material module of abaqus the moony-rivlin can be defined either by experimental data or coefficients (C10, C01 and D).
any help to get the data according to this method?

As a baseline, you just need uniaxial stress strain data, just like for any other material model. I believe the Abaqus docs outline other possible tests (biaxial, triaxial, shear, etc) as well.
