Constructor & Destructor Documentation

§ DruckerPrager()

template<int dim>

aspect::MaterialModel::Rheology::DruckerPrager< dim >::DruckerPrager ( )

Member Function Documentation

§ declare_parameters()

template<int dim>

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

static

Declare the parameters this function takes through input files.

§ parse_parameters()

template<int dim>

void aspect::MaterialModel::Rheology::DruckerPrager< dim >::parse_parameters	(	ParameterHandler &	prm,
		const std::unique_ptr< std::vector< unsigned int >> &	expected_n_phases_per_composition = `nullptr`
	)

Read the parameters this class declares from the parameter file. If expected_n_phases_per_composition points to a vector of unsigned integers, this is considered the number of phases for each compositional field (plus possibly a background field) and this number will be checked against the parsed parameters.

Parameters

[in]	prm	The ParameterHandler to read from.
	expected_n_phases_per_composition	Optional list of number of phases.

§ compute_drucker_prager_parameters()

template<int dim>

const DruckerPragerParameters aspect::MaterialModel::Rheology::DruckerPrager< dim >::compute_drucker_prager_parameters	(	const unsigned int	composition,
		const std::vector< double > &	phase_function_values = `std::vector< double >()`,
		const std::vector< unsigned int > &	n_phase_transitions_per_composition = `std::vector< unsigned int >()`
	)		const

Compute the parameters for the Drucker Prager plasticity. If n_phase_transitions_per_composition points to a vector of unsigned integers this is considered the number of phase transitions for each compositional field and viscosity will be first computed on each phase and then averaged for each compositional field.

§ compute_yield_stress()

template<int dim>

double aspect::MaterialModel::Rheology::DruckerPrager< dim >::compute_yield_stress	(	const double	cohesion,
		const double	angle_internal_friction,
		const double	pressure,
		const double	max_yield_stress
	)		const

Compute the plastic yield stress based on the Drucker Prager yield criterion.

§ compute_viscosity()

template<int dim>

double aspect::MaterialModel::Rheology::DruckerPrager< dim >::compute_viscosity	(	const double	cohesion,
		const double	angle_internal_friction,
		const double	pressure,
		const double	effective_strain_rate,
		const double	max_yield_stress,
		const double	non_yielding_viscosity = `std::numeric_limits< double >::infinity()`
	)		const

Compute the apparent viscosity using the yield stress and effective strain rate. If the non_yielding_viscosity is not infinite (i.e., if there are other rheological elements accommodating strain), the returned value is the effective composite viscosity, not the pure "plastic" viscosity.

§ compute_strain_rate_and_derivative()

template<int dim>

std::pair<double, double> aspect::MaterialModel::Rheology::DruckerPrager< dim >::compute_strain_rate_and_derivative	(	const double	stress,
		const double	pressure,
		const DruckerPragerParameters	p
	)		const

Compute the strain rate and first stress derivative as a function of stress based on the damped Drucker-Prager flow law.

§ compute_derivative()

template<int dim>

double aspect::MaterialModel::Rheology::DruckerPrager< dim >::compute_derivative	(	const double	angle_internal_friction,
		const double	effective_strain_rate
	)		const

Compute the derivative of the plastic viscosity with respect to pressure.
