Member Function Documentation

void FEElasticSolidDomain::BodyForces	(	FEM &	fem,
		FESolidElement &	elem,
		vector< double > &	fe
	)		[protected]

Calculatess external body forces for solid elements.

calculates the body forces

void FEElasticSolidDomain::BodyForceStiffness	(	FEM &	fem,
		FESolidElement &	el,
		matrix &	ke
	)		[protected]

calculates the stiffness matrix due to body forces

This function calculates the stiffness due to body forces.

void FEElasticSolidDomain::ElementInertialStiffness	(	FEM &	fem,
		FESolidElement &	el,
		matrix &	ke
	)		[protected]

calculates the solid element inertial stiffness matrix

calculates element inertial stiffness matrix

void FEElasticSolidDomain::ElementStiffness	(	FEM &	fem,
		int	iel,
		matrix &	ke
	)		[virtual]

calculates the solid element stiffness matrix

This function calculates the element stiffness matrix. It calls the material stiffness function, the geometrical stiffness function and, if necessary, the dilatational stiffness function. Note that these three functions only calculate the upper diagonal matrix due to the symmetry of the element stiffness matrix The last section of this function fills the rest of the element stiffness matrix.

Reimplemented in FE3FieldElasticSolidDomain, FEMultiphasicDomain, FETriphasicDomain, and FEBiphasicDomain.

void FEElasticSolidDomain::GeometricalStiffness	(	FESolidElement &	el,
		matrix &	ke
	)		[protected]

geometrical stiffness (i.e. initial stress)

calculates element's geometrical stiffness component for integration point n

Reimplemented in FEUT4Domain.

void FEElasticSolidDomain::InternalForces	(	FESolidElement &	el,
		vector< double > &	fe
	)

Calculates the internal stress vector for solid elements.

void FEElasticSolidDomain::MaterialStiffness	(	FEM &	fem,
		FESolidElement &	el,
		matrix &	ke
	)		[protected]

material stiffness component

Calculates element material stiffness element matrix.

Reimplemented in FEUT4Domain.

void FEElasticSolidDomain::Residual	(	FESolidSolver *	psolver,
		vector< double > &	R
	)		[virtual]
