Product: Abaqus/CAE
Benefits: You can now create materials with anisotropic hyperelastic behavior in Abaqus/CAE. This enhancement augments the feature set available in Abaqus/CAE.
Description: This feature provides a general capability for modeling materials that exhibit highly anisotropic and nonlinear elastic behavior; for example, biomedical soft tissues and fiber-reinforced elastomers. The material editor for defining anisotropic hyperelastic materials is shown in Figure 7–2.
Several forms of strain energy potential are available for anisotropic hyperelastic materials: the generalized Fung form (including fully anisotropic and orthotropic cases), the Holzapfel form for arterial walls, and user-defined forms (strain-based and invariant-based). This material model can also be used in combination with large-strain time-domain viscoelasticity.
