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.
Description of how to plot the viscoplastic strain magnitude when using PolyUMod or MCalibration.
Summary of the key new features of version 6.1.0 of MCalibration and PolyUMod.
In this article I will show how to use the Abaqus *Hysteresis model. The specific focus is on when to use Hybrid elements.
PolyUMod is a library of advanced user material models for Abaqus, ANSYS, LS-DYNA, MSC Marc, and COMSOL.
A case study aimed at showing how to use the different cohesive elements and surface models available in Abaqus.
The Bergstrom-Boyce (BB) model is a powerful model for elastomers. This post graphically demonstrates what the material parameters mean.
Tutorial on how to importing the Abaqus results from one PolyUMod simulation to another
Tutorial on how to simulate how much a part heats up due to dissipated energy. The example is using Abaqus/Explicit and the PolyUMod library.
Summary of the TNV model from the PolyUMod library. The TNV model can accurately predict the mechanical response of almost all polymers.
