Anisotropic hyperelastic behavior

The anisotropic hyperelastic material model:

  • provides a general capability for modeling materials that exhibit highly anisotropic and nonlinear elastic behavior (such as biomedical soft tissues, fiber-reinforced elastomers, etc.);

  • can be used in combination with large-strain time-domain viscoelasticity (Time domain viscoelasticity); however, viscoelasticity is isotropic;

  • optionally allows the specification of energy dissipation and stress softening effects (see Mullins effect); and

  • requires that geometric nonlinearity be accounted for during the analysis step (General and perturbation procedures) since it is intended for finite-strain applications.
