Detailed Description

This law defines an hyperelastic material according to the Saint-Venant–Kirchhoff formulation for 3D cases.

The simplest hyperelastic material model is the Saint Venant–Kirchhoff model which is just an extension of the linear elastic material model to the nonlinear regime. More info https://en.wikipedia.org/wiki/Hyperelastic_material#Saint_Venant%E2%80%93Kirchhoff_model

◆ Check()

int Kratos::HyperElasticIsotropicKirchhoff3D::Check ( const Properties rMaterialProperties,
const GeometryType rElementGeometry,
const ProcessInfo rCurrentProcessInfo 
) const
overridevirtual

This function provides the place to perform checks on the completeness of the input.

It is designed to be called only once (or anyway, not often) typically at the beginning of the calculations, so to verify that nothing is missing from the input or that no common error is found.

Parameters
rMaterialPropertiesThe properties of the material
rElementGeometryThe geometry of the element
rCurrentProcessInfoThe current process info instance

Reimplemented from Kratos::ConstitutiveLaw.

◆ Clone()

ConstitutiveLaw::Pointer Kratos::HyperElasticIsotropicKirchhoff3D::Clone ( ) const
