PolyUMod Overview
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!
MCalibration
Selecting and calibrating a suitable material model can be very challenging. The MCalibration software makes that task easy! It can calibrate all PolyUMod material models, and most built-in models in FE solvers.

What Material Model Can Predict Different Stiffnesses in Tension and Compression?
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.
How to Force Drucker’s Stability in MCalibration
A material model is considered Drucker’s stable if an increase in strain results in an increase in stress. In some cases it can be important to enforce that a material model is Drucker’s stable. This article shows how you can easily achieve this in MCalibration.
