Material Model Name

Materials

Linear Elastic (LE)

Linear elastic model that also incorporates the PolyUMod failure models.

Neo-Hookean (NH)

Neo-Hookean hyperelastic model that supports the PolyUMod failure models.

Eight-Chain (EC)

Arruda-Boyce eight-chain hyperelastic model that supports the PolyUMod failure models. [J. Mech. Phys. Solids, 41, 389-412, 1993]

Uses a more accurate implementation of the inverse Langevin function than most other commercial implementations.

Anisotropic Eight-Chain (AEC)

Anisotropic version of the eight-chain model [Bischoff et al, Trans. ASME, 69, 570-579, 2002].

Supports different failure models.

Bergstrom-Boyce (BB)

Advanced material model for elastomers, rubbers, and soft biological tissues [Mech. Materials, 33, 523-530, 2001].

Adds functionality to the built-in option in ABAQUS/Implicit and ANSYS:

• Temperature effects
• Available for ABAQUS/Explicit

Supports different failure models.

BB Mullins (BBM)

Same as standard BB model, but also includes the Ogden-Roxburgh Mullins model [Proceedings of the Royal Society of London, Series A, 455, 2861-2877, 1999].

Adds functionality to the built-in *Hysteresis option in ABAQUS/Implicit:

• Temperature effects
• Mullins effect
• Available for ABAQUS/Explicit

Supports different failure models.

Anisotropic BB Mullins (ABBM)

Same as the BBM model but is using the Bischoff anisotropic eight-chain model.

• Temperature effects
• Anisotropic
• Mullins effect
• Strain-rate effects
• Available for explicit simulations

Supports different failure models.

Dynamic Bergstrom-Boyce (DBB)

Same as the BBM model but contains additional features to enable accurate predictions of both small-strain dynamic behavior and large-strain behavior using one set of material parameters.

• Temperature effects
• Small strain dynamic behavior
• Mullins effect

Supports different failure models.

Parallel Network (PNM)

Advanced model that contains an arbitrary number of elastic and flow elements connected in parallel.

• Suitable for large deformation, thermomechanical predictions of many different classes of polymers.

Supports different failure models.
