Tutorial on how to make the PolyUMod TN and TNV models better capture the stiffness non-linearity before yielding.
Version 6.4.0 of PolyUMod includes 2 advanced UCREEPNETWORK and VUCREEPNETWORK models that can be used with the Abaqus PRF model.
Tutorial on how and when to set the ORIENT flag with using Abaqus and an anisotropic material model from the PolyUMod material model.
In this video I will show have to make most Abaqus/Standard simulations that use the PolyUMod library run faster (and with larger time increments). The key is to set an Abaqus time incrementation setting.
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.
