Member Function Documentation

bool FE3FieldElasticSolidDomain::Augment

(

)

augmentation

Do augmentation.

void FE3FieldElasticSolidDomain::DilatationalStiffness	(	FEM &	fem,
		int	iel,
		matrix &	ke
	)		[protected]

Dilatational stiffness component for nearly-incompressible materials.

calculates dilatational element stiffness component for element iel

void FE3FieldElasticSolidDomain::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 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 from FEElasticSolidDomain.

void FE3FieldElasticSolidDomain::GeometricalStiffness	(	int	iel,
		matrix &	ke
	)		[protected]

geometrical stiffness (i.e. initial stress)

calculates element's geometrical stiffness component for each integration point

void FE3FieldElasticSolidDomain::MaterialStiffness	(	FEM &	fem,
		int	iel,
		matrix &	ke
	)		[protected]

material stiffness component

Calculates element material stiffness element matrix.

void FE3FieldElasticSolidDomain::Serialize

(

DumpFile &

ar

)

[virtual]

serialize data to archive

Data serialization.

Reimplemented from FESolidDomain.

void FE3FieldElasticSolidDomain::UpdateStresses

(

FEModel &

fem

)

[virtual]

This function updates the stresses for elements using the three-field formulation. For such elements, the stress is a sum of a deviatoric stress, calculate by the material and a dilatational term.

Reimplemented from FEElasticSolidDomain.
