Part 1: Tutorial on how to predict the cold drawing or necking response of thermoplastics (such as polycarbonate).
Tutorial on how to make the PolyUMod TN and TNV models better capture the stiffness non-linearity before yielding.
This article examines which material model is best for PEEK. Some of the basic plasticity models are surprisingly bad.
Demonstration of how to accurately predict the deformation response of a soda bottle under internal pressure.
Demo of how to simulate a Teflon seal using Ansys using a viscoplastic material model, without any experimental data.
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.
Instructions for how to make sure Ansys Mechanical finds and uses a PolyUMod material model.
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.
Summary of the key new features of version 6.1.0 of MCalibration and PolyUMod.
This article illustrates how the PolyUMod state variables can be plotted in ANSYS Workbench.
PolyUMod is a library of advanced user material models for Abaqus, ANSYS, LS-DYNA, MSC Marc, and COMSOL.
