LLDPE Material Modeling
Demonstration of how you can use the PolyUMod Material Database model for LLDPE. This is an excellent model for generic LLDPE.

Part 2: Calibrating a material model from tension with necking experimental data is surprisingly difficult. This article explains one approach to do it.
Abaqus 2022 contains some really nice improvements for Linux users. This article summarizes the key improvements.
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.
Version 6.4.0 of PolyUMod includes 2 advanced UCREEPNETWORK and VUCREEPNETWORK models that can be used with the Abaqus PRF model.
Tutorial on how and when to set the ORIENT flag with using Abaqus and an anisotropic material model from the PolyUMod material model.
In this video I will show have to make most Abaqus/Standard simulations that use the PolyUMod library run faster (and with larger time increments). The key is to set an Abaqus time incrementation setting.
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.
