declare_parameters()

template<int dim>

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

compute_strain_weakening_factors() [1/2]

template<int dim>

std::array<double, 3> aspect::MaterialModel::Rheology::StrainDependent< dim >::compute_strain_weakening_factors	(	const std::vector< double > &	composition,
		const unsigned int	j
	)		const

A function that computes by how much the rheologic parameters change if strain weakening is applied. Given a vector composition of all fields, it returns reduction factors for the cohesion, friction angle and the prefactor of the viscous flow law(s) for the compositional field with index j. The reason all fields are passed is that the weakening factors can depend on the values of fields that track different measures of previously applied strain.
