What model should I use with the following data?

[haesung]

Hello,

I like to know what constitutive model of elastomer I have to use, given the data as attached or the name of material in PS.
Any suggestion or idea for best-fiit hyperelastic model for the material?

Thanks,
Haesung

P.S.: the material is NBR B7150 (Acrylonitrile Butadiene Rubber).

Which material model that is the most appropriate will depend on the application. If you want to use a hyperelastic model, then you have a number of potential candidates. I personally like the Arruda-Boyce eight-chain model, the Yeoh model, and the neo-Hookean model.

Note that your attachment does not contain enough information to calibrate a hyperelastic material model (except perhaps the neo-Hookean model).
