Foam Library

The foam library contains the following subroutines.  Each of these models provides unique and powerful predictions for different classes of open- and closed-cell foams.  Each material model is available for both implicit and explicit finite element simulations.

Material Model Name Description
Linear Elastic Model
Linear Elastic (LE)
Linear elastic model that also incorporates the PolyUMod failure models.
Micromechanical Foam Model
Micromechanical Foam Model (MFM)
Polymer foam model that explicitly incorporates the reduced density of the foam.
  • Large deformation behavior
  • Strain-rate effects
  • Temperature effects
  • Explicitly incorporates the reduced density of the foam
  • Supports different failure models
Three Network Foam Model
Three Network Foam (TNFM
Version of the TNM that is explicitly formulated to polymer foams.
  • Supports different failure models
