Hello all,

I find this forum is very informative. I have one doubt in material modeling. Is uni axial compression data sufficient to fit mooney rivlin model?

Or do we need biaxial data to check whether a particular model is fit for incompressible material.

if one of mooney rivlin coefficients (say c10) is negative can we say Mooney is inappropriate for that material as per Baker Ericksen inequalities.

Please provide ur suggestions. thanks in advance.

Regards

Kavitha
