How to Simulate a Teflon Seal using Ansys
Demo of how to simulate a Teflon seal using Ansys using a viscoplastic material model, without any experimental data.
What Material Model Can Predict Different Stiffnesses in Tension and Compression?
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.
How to Make Ansys find PolyUMod
Instructions for how to make sure Ansys Mechanical finds and uses a PolyUMod material model.
Extended Tube Model in Ansys Mechanical
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.
New Features: Version 6.1.0
Summary of the key new features of version 6.1.0 of MCalibration and PolyUMod.
Plot PolyUMod State Variables in ANSYS
This article illustrates how the PolyUMod state variables can be plotted in ANSYS Workbench.
Introduction to PolyUMod®
PolyUMod is a library of advanced user material models for Abaqus, ANSYS, LS-DYNA, MSC Marc, and COMSOL.
Bergstrom-Boyce (BB) Model Parameters
The Bergstrom-Boyce (BB) model is a powerful model for elastomers. This post graphically demonstrates what the material parameters mean.
