ModifiedHGO

Definition of elastic behaviour using a Modified Holzapfel-Gasser-Ogden anisotropic hyperelastic model.

Selecting this model will trigger a non-linear solve and will require adding a spatial distribution.

Fields

• a_sheet: String, default = ""

  Linear constant in the sheet direction (y'). (required)

• b_sheet: String, default = ""

• bulk_modulus: String, default = ""

  Bulk modulus of elasticity. (required)

• spatial_distribution: String, default = ""
