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.
Introduction to how MCalibration and PolyUMod can be used with Altair Radioss. This is a great starting point if you are new to our software.
Complete step-by-step tutorial on how to use HyperMesh to setup a Radioss FE model with a PolyUMod material model.
Short tutorial on how to run Radioss with the PolyUMod library from the command line.
Summary of the key new features of version 6.1.0 of MCalibration and PolyUMod.
PolyUMod is a library of advanced user material models for Abaqus, ANSYS, LS-DYNA, MSC Marc, and COMSOL.
Demonstrate how to use a PolyUMod material model with the Radioss explicit FE solver. Information about how to select and calibrate a PolyUMod material model is presented in our “MCalibration for Altair” tutorial.
The Bergstrom-Boyce (BB) model is a powerful model for elastomers. This post graphically demonstrates what the material parameters mean.
Summary of the TNV model from the PolyUMod library. The TNV model can accurately predict the mechanical response of almost all polymers.
