Tutorial on how to make the PolyUMod TN and TNV models better capture the stiffness non-linearity before yielding.
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.
Introduction to how MCalibration and PolyUMod can be used with Altair Radioss. This is a great starting point if you are new to our software.
