The J-Integral is the key quantity of Elastic-Plastic Fracture Mechanics (EPFM). This article shows how to derive it from first principles.
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.
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.
