The Elastomer library contains the following subroutines. Each of these models provides unique and powerful predictions for different classes of elastomers, rubbers, and biopolymers. Each material model is available for both implicit and explicit FE simulations.
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. |
