Calibrate the BB-Model using a Single Experiment
It is possible to calibrate a two-network visco-plastic material model to experimental data from a single experiment. This article explains how to do it.

Review of different creep models that are available in Ansys Mechanical. In the article I will recommend which to use and which to avoid.
Tutorial on Abaqus creep laws, which 2 you should not use, and which are the best. I also discuss how creep models work for polymers.
Article discussing how isotropic hardening plasticity works, when you should use it, and issues that can occur if you use it incorrectly.
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.
This article presents 3 reasons the Poisson’s ratio is not useful, and also explains how you can fix the problems.
Part 1: Tutorial on how to predict the cold drawing or necking response of thermoplastics (such as polycarbonate).
The Blatz-Ko model can be used for both foams and rubber-like materials. This article explains the theory.
Anisotropic materials often need an effective strain measure. The Hill strain is useful in those cases.
