To perform Finite Element (FE) simulations of filled elastomers it is necessary to first calibrate a material model to set of given experimental data. To get a representative and accurate set of material parameters it is important to use experimental data from a collection of different experimental tests. If not, it possible that the calibrated material model will not work accurately in a different loading mode than what was used for the calibration. I have recently analyzed a set of experimental data for filled Natural Rubber (NR) filled with 55 parts per hundred (pph) carbon black (CB)...
This material was tested in uniaxial tension, planar tension, and biaxial tension. The experiments were performed at room temperature under quasi-static loading conditions (i.e. the applied strain rate was very slow). A number of different hyperelastic material models where then fitted to the experimental data, and the accuracy of the different models, evaluated using the R2-value, was compared. The results from this study is presented in the Materials and Models section (http://polymerfem.com/cmps_index.php?pageid=mat_mod).
