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!
How to run COMSOL Multiphysics using an input file and a command prompt. It is easy using the Java API.
Guide to using MCalibration and PolyUMod with COMSOL Multiphysics. A complete start-to-finish tutorial is presented.
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.
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.
