,nWhich model is the 'best' is usually determined by how closely it fits your experimental testing data. If you check the literature you would find several models being used for styrene-butadiene rubber, each of which give accurate results. If you do not have the experimental data, you could refer a good article in the literature, use the test data and try out different models that are available in ANSYS and check which fits the best. You could check out different models 4.6. Hyperelasticity (ansys.com), testing and curve fitting procedure 6.1. Hyperelastic Material Curve-Fitting (ansys.com).nRegards,nIshan. n
