Member Function Documentation

int oofem::StructuralInterfaceCrossSection::checkConsistency ( )

For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns: Nonzero if receiver is consistent.

inline

Computes the real stress vector for given strain and integration point.

The service should use previously reached equilibrium history variables. Also it should update temporary history variables in status according to newly reached state. The temporary history variables are moved into equilibrium ones after global structure equilibrium has been reached by iteration process. Elements should always pass their requests to their cross section model, which performs necessary integration over its volume and invokes necessary material services for corresponding material model defined for given integration point.

Parameters

answer	Contains result.
gp	Integration point.
reducedF	Deformation gradient in reduced form.
tStep	Current time step (most models are able to respond only when tStep is current time step).

IRResultType oofem::StructuralInterfaceCrossSection::initializeFrom ( InputRecord * ir )

Parameters

ir	Input record to initialize from.

Returns: IRResultType

int oofem::StructuralInterfaceCrossSection::packUnknowns	(	DataStream &	buff,
		TimeStep *	tStep,
		GaussPoint *	ip
	)

virtual

Pack all necessary data of integration point (according to element parallel_mode) into given communication buffer.

The corresponding material model service for particular integration point is invoked. The nature of packed data is material model dependent. Typically, for material of "local" response (response depends only on integration point local state) no data are exchanged. For "nonlocal" constitutive models the send/receive of local values which undergo averaging is performed between local and corresponding remote elements.

Parameters
