I am comparing the answers from various hyperelastic models in Algor Simulation MES 2011. I get solutions with Mooney Rivlin and Neohookean but Yeoh is not working.
In general, material properties are important in these rubber material models.
No idea on your numbers.
My simple testing model works fine with the following material properties:
density=1e-5, c10=2e5,c20=3e5,c30=4e5,k1=297,k2=497,k3=697.
Please let us know your further testing results.
Thanks.
