Detailed Description

Abstract base class for all structural interface elements. It declares a common interface available to all derived elements. The implementation of these services is partly left to the derived classes, some general services are implemented here (but they can be overload by more efficient element implementations). The general implementation provided here is intended for both linear and nonlinear computations.

Member Function Documentation

◆ checkConsistency()

int oofem::StructuralInterfaceElement::checkConsistency ( void )

overridevirtual

Performs consistency check. This method is called at startup for all elements in particular domain. This method is intended to check data compatibility. Particular element types should test if compatible material and crossSection both with required capabilities are specified. Derived classes should provide their own analysis specific tests. Some printed input if incompatibility is found should be provided (error or warning member functions). Method can be also used to initialize some variables, since this is invoked after all domain components are instanciated.

Returns: Zero value if check fail, otherwise nonzero.

◆ computeStiffnessMatrix()

void oofem::StructuralInterfaceElement::computeStiffnessMatrix	(	FloatMatrix &	answer,
		MatResponseMode	rMode,
		TimeStep *	tStep )

virtual

Computes the stiffness/tangent matrix of receiver. Default implementation computes element stiffness using \( K=\int_{\Gamma} N^{\mathrm{T}} D N \mathrm{d}V \) formulae, where \( N \) is the element geometric matrix such that \( j = N a \) and \( D \) is the stiffness matrix of the interface material. Numerical integration procedure uses integrationRulesArray for numerical integration.

The geometrical matrix is obtained using computeNmatrixAt service and the constitutive matrix is obtained using computeConstitutiveMatrixAt service.

For higher numerical performance, only one half of stiffness matrix is computed and answer is then symmetrized. Therefore, if element matrix will be generally nonsymmetric, one must specialize this method. Finally, the result is transformed into global coordinate system (or nodal coordinate system, if it is defined).

Parameters

answer	Computed stiffness matrix (symmetric).
rMode	Response mode.
tStep	Time step.

◆ giveInternalForcesVector()

void oofem::StructuralInterfaceElement::giveInternalForcesVector	(	FloatArray &	answer,

virtual

Returns equivalent nodal forces vectors. Useful for nonlinear analysis. Default implementation computes result as \( F=\int_v B^{\mathrm{T}} \sigma \mathrm{d}V \), where \( \sigma \) is the real element stress vector obtained using computeStressVector service (if useUpdatedGpRecord=0) or (if useUpdatedGpRecord=1) from integration point status. The geometric matrix is obtained using computeBmatrixAt service. Integration is performed using default integration rule, which should produce always valid results, assuming that strains used for computation of stresses are valid.

Parameters

answer	Internal nodal forces vector.
tStep	Time step.
useUpdatedGpRecord	If equal to zero, the stresses in integration points are computed (slow but safe), else if nonzero the stresses are taken directly from integration point status (should be derived from StructuralMaterialStatus) (fast, but engineering model must ensure valid status data in each integration point).

type	Determines the type of internal variable.
tStep	Time step.

Returns: Nonzero if o.k, zero otherwise.

Todo: Which "error type" should be used? Why are there several? I don't see the point of this enum when there could be different function calls just as well (and different IST values)

◆ giveNumberOfIPForMassMtrxIntegration()

virtual int oofem::StructuralInterfaceElement::giveNumberOfIPForMassMtrxIntegration ( )

inlineprotectedvirtual

Return desired number of integration points for consistent mass matrix computation, if required.

Returns: Number of integration points for mass matrix.

Todo: not sure if we should allow these elements to have mass - JB

Todo: dT1dj = d(F*T2)/dj = dF/dj*T2 + F*dT2/dj - should we assume dFdj = 0? Otherwise it will be very complex!

◆ testElementExtension()

int oofem::StructuralInterfaceElement::testElementExtension ( ElementExtension ext )

inlineoverrideprotectedvirtual

Tests if the element implements required extension. ElementExtension type defines the list of all available element extensions.

Parameters

ext	Extension to be tested.

Returns: Nonzero if extension supported.

◆ updateInternalState()

void oofem::StructuralInterfaceElement::updateInternalState ( TimeStep * tStep )

overridevirtual

Updates element state after equilibrium in time step has been reached. Default implementation updates all integration rules defined by integrationRulesArray member variable. Doing this, all integration points and their material statuses are updated also. All temporary history variables, which now describe equilibrium state are copied into equilibrium ones. The existing internal state is used for update.

Parameters

tStep Time step for newly reached state.

◆ updateYourself()

void oofem::StructuralInterfaceElement::updateYourself ( TimeStep * tStep )
