computeConstitutiveRelation()

template<int DisplacementDim>

virtual void MaterialLib::Fracture::FractureModelBase< DisplacementDim >::computeConstitutiveRelation ( double const t, ParameterLib::SpatialPosition const & x, double const aperture0, Eigen::Ref< Eigen::VectorXd const > sigma0, Eigen::Ref< Eigen::VectorXd const > w_prev, Eigen::Ref< Eigen::VectorXd const > w, Eigen::Ref< Eigen::VectorXd const > sigma_prev, Eigen::Ref< Eigen::VectorXd > sigma, Eigen::Ref< Eigen::MatrixXd > C, MaterialStateVariables & material_state_variables )

pure virtual

Computation of the constitutive relation for specific material model. This should be implemented in the derived model.

Parameters

t	current time
x	current position in space
aperture0	initial fracture's aperture
sigma0	initial stress
w_prev	fracture displacement at previous time step
w	fracture displacement at current time step
sigma_prev	stress at previous time step
sigma	stress at current time step
C	tangent matrix for stress and fracture displacements
material_state_variables	material state variables

createMaterialStateVariables()

template<int DisplacementDim>

virtual std::unique_ptr< MaterialStateVariables > MaterialLib::Fracture::FractureModelBase< DisplacementDim >::createMaterialStateVariables ( )

pure virtual

Polymorphic creator for MaterialStateVariables objects specific for a material model.

Implemented in MaterialLib::Fracture::CohesiveZoneModeI::CohesiveZoneModeI< DisplacementDim >, MaterialLib::Fracture::Coulomb::Coulomb< DisplacementDim >, and MaterialLib::Fracture::LinearElasticIsotropic< DisplacementDim >.
