Calibrating the Mooney-Rivlin Model
The Mooney-Rivlin model be calibrated to monotonic uniaxial tension data, but in most cases it is better to use more experimental data.

Summary of 4 things that are important to know about the Ogden model. It is a very powerful model, but it can be difficult to use correctly.
The Arruda-Boyce Eight-Chain model is a micromechanism-inspired hyperelastic model that works very well. This article explains the theory.
It is easy to quickly calibrate a temperature-dependent Abaqus Hyperelastic model. This article shows how using MCalibration.
It is easy to quickly calibrate a temperature-dependent Ansys Hyperelastic model. This article shows how using MCalibration.
One way to quickly improve the accuracy of the Arruda-Boyce model is to add one more strain energy funcion.
Gent hyperelasticity theory and parameter calibration. The Gent model is available in Ansys Mechanical and COMSOL Multiphysics.
The Blatz-Ko model can be used for both foams and rubber-like materials. This article explains the theory.
Demonstration of how you can quickly calibrate the Extended Tube Model that is available in COMSOL Multiphysics.
The Extended Tube model is one of the most accurate hyperelastic material models available, but it can be difficult to use if you don’t understand how the material parameters influence the predicted stress-strain response. This article will demonstrate that by example.
Here’s a summary of 5 common mistakes when using Hyperelasticity in a FE model. I see these errors frequently, so read this article to make sure you don’t make them too.
The theory behind the common Hyperfoam, Ogden foam, and Hill foam models. Also covers how to calibrate these useful models.
