A quick review of Linear Elastic Fracture Mechanics (LEFM), and how it applies to thermoplastics and other polymers.
Article about creep rupture behavior of different thermoplastics, and how you can predict creep rupture in a FE simulation.
Article presenting the Christensen’s failure theory for materials under monotonic loading. The theory is compared to UHMWPE data.
You can predict failure of thermoplastics under monotonic loading using a strain-based failure condition with triaxiality dependence.
Tutorial on how to use a PolyUMod material model in LS-DYNA using Ansys Workbench. The most important set is to use the PolyUMod executable.
The Drucker Stability condition is well know, but not trivial to understand. This article explains what this condition means, and how to use it in your own work.
This article explains different techniques that can be used when calibrating a material model when you have experimental data from multiple repeated experiments.
Did you know that there are 2 different ways to create a temperature-dependent material model? This article explains the details.
