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.
