Here is a calibrated material model for a generic polypropylene (PP) tested at room temperature. To use this material model you will need to first install the MCalibration software, and then export the model to your favorite FE software. The calibrated material model is the PolyUMod Three Network (TN) model.
In large deformations, simple shear is not so simple. This article describes how to properly test and analyze shear behavior.
Soft polymer foams, and some other materials, often exhibit different stiffnesses in uniaxial tension and compression. Most material models cannot predict this type of behavior, but there are some excellent choices for this.
Part 3 in our series on how to calibrate a material model from tension force data. This article focuses on using Abaqus for the calculations.
