Hyperelastic material model verification?
I am working to model a material using Mooney-Rivlin (MR) model. I have the experimental data. I used the curve fitting tool in ansys to find the coefficients of MR model. Now I want to verify the model with simulation. I made a cylindrical sample of material and I have given it the displacement equivalent to strain in material during experiment so that it gets loaded under same strain rate. Now the Von-Mises stresses I am getting from the simulation are not matching the experimental values as I have used the same experimental data to drive its model. I think conversely it should give similar stress under similar loading. Can anybody help me in this regarding?
