Member Function Documentation

§ declare_parameters()

template<int dim>

static void aspect::MaterialModel::Rheology::Elasticity< dim >::declare_parameters ( ParameterHandler & prm )

static

Declare the parameters this function takes through input files.

§ parse_parameters()

template<int dim>

void aspect::MaterialModel::Rheology::Elasticity< dim >::parse_parameters ( ParameterHandler & prm )

Read the parameters from the parameter file.

§ create_elastic_outputs()

template<int dim>

void aspect::MaterialModel::Rheology::Elasticity< dim >::create_elastic_outputs ( MaterialModel::MaterialModelOutputs< dim > & out ) const

Create the additional material model outputs object that contains the elastic shear moduli.

§ fill_elastic_outputs()

template<int dim>

void aspect::MaterialModel::Rheology::Elasticity< dim >::fill_elastic_outputs	(	const MaterialModel::MaterialModelInputs< dim > &	in,
		const std::vector< double > &	average_elastic_shear_moduli,
		MaterialModel::MaterialModelOutputs< dim > &	out
	)		const

Given the stress of the previous time step in the material model inputs in, the elastic shear moduli average_elastic_shear_moduli a each point, and the (viscous) viscosities given in the material model outputs object out, fill an additional material model outputs objects with the elastic force terms.

§ fill_reaction_outputs()

template<int dim>

void aspect::MaterialModel::Rheology::Elasticity< dim >::fill_reaction_outputs	(	const MaterialModel::MaterialModelInputs< dim > &	in,
		const std::vector< double > &	average_elastic_shear_moduli,
		MaterialModel::MaterialModelOutputs< dim > &	out
	)		const

Given the stress of the previous time step in the material model inputs in, the elastic shear moduli average_elastic_shear_moduli a each point, and the (viscous) viscosities given in the material model outputs object out, compute an update to the elastic stresses and use it to fill the reaction terms material model output property.

§ get_elastic_shear_moduli()

template<int dim>

const std::vector<double>& aspect::MaterialModel::Rheology::Elasticity< dim >::get_elastic_shear_moduli ( ) const

Return the values of the elastic shear moduli for each composition used in the rheology model.

§ calculate_elastic_viscosity()

template<int dim>

double aspect::MaterialModel::Rheology::Elasticity< dim >::calculate_elastic_viscosity ( const double shear_modulus ) const

Calculates the effective elastic viscosity (this is the equivalent viscosity of a material which was unstressed at the end of the previous timestep).

§ calculate_viscoelastic_viscosity()

template<int dim>

double aspect::MaterialModel::Rheology::Elasticity< dim >::calculate_viscoelastic_viscosity	(	const double	viscosity,
		const double	shear_modulus
	)		const

Given the (viscous or visco-plastic) viscosity and the shear modulus, compute the viscoelastic viscosity (eqn 28 in Moresi et al., 2003, J. Comp. Phys.).

§ calculate_viscoelastic_strain_rate()

template<int dim>

SymmetricTensor<2,dim> aspect::MaterialModel::Rheology::Elasticity< dim >::calculate_viscoelastic_strain_rate	(	const SymmetricTensor< 2, dim > &	strain_rate,
		const SymmetricTensor< 2, dim > &	stored_stress,
		const double	shear_modulus
	)		const

Calculate the effective deviatoric strain rate tensor, which equals the true deviatoric strain rate plus a fictional strain rate which would arise from stored elastic stresses. In ASPECT, this additional strain rate is supported by a fictional body force. This formulation allows the use of an isotropic effective viscosity by ensuring that the resulting strain rate tensor is equal to the total current stress tensor multiplied by a scalar.

§ elastic_timestep()

template<int dim>

double aspect::MaterialModel::Rheology::Elasticity< dim >::elastic_timestep ( ) const

Compute the elastic time step.

Member Data Documentation

§ elastic_damper_viscosity

template<int dim>

double aspect::MaterialModel::Rheology::Elasticity< dim >::elastic_damper_viscosity

private

Viscosity of a damper used to stabilize elasticity. A value of 0 Pas is equivalent to not using a damper.

Definition at line 156 of file elasticity.h.

§ elastic_shear_moduli

template<int dim>

std::vector<double> aspect::MaterialModel::Rheology::Elasticity< dim >::elastic_shear_moduli

private

Vector for field elastic shear moduli, read from parameter file.

Definition at line 161 of file elasticity.h.

§ use_fixed_elastic_time_step

template<int dim>

bool aspect::MaterialModel::Rheology::Elasticity< dim >::use_fixed_elastic_time_step

private

Bool indicating whether to use a fixed material time scale in the viscoelastic rheology for all time steps (if true) or to use the actual (variable) advection time step of the model (if false). Read from parameter file.

Definition at line 169 of file elasticity.h.

§ fixed_elastic_time_step

template<int dim>

double aspect::MaterialModel::Rheology::Elasticity< dim >::fixed_elastic_time_step

private

Double for fixed elastic time step value, read from parameter file

Definition at line 174 of file elasticity.h.

§ stabilization_time_scale_factor

template<int dim>

double aspect::MaterialModel::Rheology::Elasticity< dim >::stabilization_time_scale_factor

private

A stabilization factor for the elastic stresses that influences how fast elastic stresses adjust to deformation. 1.0 is equivalent to no stabilization, and infinity is equivalent to not applying elastic stresses at all. The factor is multiplied with the computational time step to create a time scale.

Definition at line 183 of file elasticity.h.

§ evaluator

template<int dim>

std::unique_ptr<FEPointEvaluation<dim, dim> > aspect::MaterialModel::Rheology::Elasticity< dim >::evaluator

mutableprivate

We cache the evaluator that is necessary to evaluate the old velocity gradients. They are required to compute the elastic stresses, but are not provided by the material model. By caching the evaluator, we can avoid recreating it every time we need it.
