Linear Elastic Fracture Mechanics
A quick review of Linear Elastic Fracture Mechanics (LEFM), and how it applies to thermoplastics and other polymers.
Essential tools for your finite element (FE) analysis! MCalibration® can quickly calibrate almost any material model. The PolyUMod® library is a plugin to your FE solver that contains the most accurate material models available!
In many important applications the material response is sufficiently non-linear that simple hyperelasticity or metal plasticity is not good enough. In these cases the PolyUMod library can be very useful since it contains a selection of the most advanced and accurate material models that are currently available. The PolyUMod library is easy to use and can give you a significant competitive advantage!
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.
