Member Function Documentation

applyViscosityOnStateVar()

template<int s>

double Marmot::ContinuumMechanics::CommonConstitutiveModels::DuvautLionsViscosity< s >::applyViscosityOnStateVar	(	double	stateVarTrial,
		double	StateVarInf,
		double	dT
	)

Apply viscosity on a scalar internal variable depending on the extremal solutions for t=0 (trialState) and t= \(\infty\), and timestep dt

applyViscosityOnStress()

template<int s>

Marmot::Vector6d Marmot::ContinuumMechanics::CommonConstitutiveModels::DuvautLionsViscosity< s >::applyViscosityOnStress	(	const Marmot::Vector6d &	trialStress,
		const Marmot::Vector6d &	stressInf,
		double	dT
	)

Apply viscosity on voigt sized rank two tensor depending on the extremal solutions for t=0 (trialState) and t= \(\infty\), and timestep dt

applyViscosityOnMatTangent()

template<int s>

DuvautLionsViscosity< s >::TangentSizedMatrix Marmot::ContinuumMechanics::CommonConstitutiveModels::DuvautLionsViscosity< s >::applyViscosityOnMatTangent	(	const TangentSizedMatrix &	matTangentInv,
		double	dT
	)

Apply viscosity on the inverse (algorithmic) material tangent depending on the extremal solutions for t=0 (trialState) and t= \(\infty\), and timestep dt

Todo:

: Check if application to inverse can be replaced by application to non-inverse in general
