This material model predicts the non-linear viscoelastic response of elastomer-like materials. 

The Bergstrom-Boyce model with enhanced Ogden-Roxburgh Mullins effect (BBM) is a variant of the BB model. The key difference is that the eight-chain hyperelastic Network A includes a Mullins damage term, enhancing its predictive capabilities.

The anisotropic BB model with Mullins damage is an extension of the original BB model in which the hyper elastic response is captured using the anisotropic eight-chain model.

The Hybrid model (HM) predicts the large deformation, time-dependent response of UHMWPE. The HM is typically less advanced than the Three Network (TN) model, which is also entirely accurate for UHMWPE and other thermoplastics.

The Dual Network Fluoropolymer (DNF) model predicts Fluoropolymers' large-strain, viscoplastic response. The model is based on three parallel networks and supports volumetric flow.

The Three Network (TN) model predicts generic thermoplastic materials' large-strain, viscoplastic response (in a glassy state). The TN model is an excellent generic model for predicting the response of many different amorphous and semicrystalline thermoplastics classes.

The micromechanical foam model (MFM) is an advanced model for predicting polymer foams' time-dependent, non-linear large-strain behavior. 

The three-network foam model (TNFM) is a material developed explicitly for thermoplastic materials available as foam. It combines the three-network model (TNM) and the microfoam model (MFM). The TNFM explicitly incorporates the effects of different reduced densities.

The Dynamic Bergström-Boyce (DBB) model is an advanced constitutive model specifically developed to predict the time-dependent, dynamic, large-strain behavior of elastomer-like materials. It is an extension of the BB model.

The Silberstein-Boyce model (SB) predicts the large strain, time, temperature, and hydration-dependent response of Nafion. This material is used as a polymer electrolyte membrane (PEM) in batteries, solar cells, and fuel cells. Its response is like that of many other thermoplastics, except that it has an unusually strong dependence on the moisture level.

The Flow Evolution Networks (FEN) model obtains an advanced multi-network model like the Parallel Network model but more numerically efficient and easier to use. The FEN model is suitable for elastomers, thermoplastics, and other isotropic thermoplastic materials.

The Three Network Viscoplastic (TNV) model is a general-purpose viscoplastic material model capable of capturing the experimentally observed behaviors of many thermoplastics, including time-dependence, pressure-dependence of plastic flow, pressure-dependent volumetric response, damage accumulation, and triaxiality-dependent failure.

The Parallel Network (PN) model is the most advanced material model in the PolyUMod library. Each network in the PN model can have an isotropic or anisotropic hyper elastic response in series with an isotropic or anisotropic viscoplastic flow element. Each element can have temperature dependence and damage evolution.
