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.
