Detailed Description

This class implements a bond link for connecting beam (frame) and continuum elements in unstructured meshes. The main idea is to use the rotation of the beam element and the rigid arm from the beam node to the continuum element node to compute the displacement jump along the rebar element (and two components, which are perpendicular to each other and lie in a plane for which the direction along the rebar is normal to. At least one node is located at the image boundary. These nodes are replaced with a periodic mirror nodes and a control node is used to impose the macroscopic (average) strain.

◆ computeStiffnessMatrix()

void oofem::BondLink3dBoundary::computeStiffnessMatrix	(	FloatMatrix &	answer,
		MatResponseMode	rMode,
		TimeStep *	tStep )

overrideprotectedvirtual

Computes numerically stiffness matrix of receiver. Default implementation computes element stiffness using \( K=\int_v B^{\mathrm{T}} D B \mathrm{d}V \) formulae, where \( B \) is element geometric matrix and \( D \) is material stiffness matrix. No geometrical nonlinearity is taken into account. NUmerical integration procedure uses integrationRulesArray for numerical integration. Support for reduced or selected integration is implemented. The individual integration rules are assumed to correspond to different terms from which the overall matrix is assembled.

If there is one integration rule, the full integration of all coefficients is performed. Otherwise, integration is performed using following rules. Each integration rule can specify start and end strain index of strain vector components for which is valid. It is necessary to ensure that these start and end indexes, dividing geometrical matrix into blocks, are not overlapping and that each strain component is included.

Then stiffness matrix is obtained as summation of integrals \( I_{ij}=\int_v B^{\mathrm{T}}_i D_{ij} B_j \mathrm{d}V \) where \( B_i \) is i-th block of geometrical matrix and \( D_{ij} \) is corresponding constitutive sub-matrix. The geometrical matrix is obtained using computeBmatrixAt service and the constitutive matrix is obtained using computeConstitutiveMatrixAt service. The \( I_{ij} \) integral is evaluated using such integration rule, which is valid for i-th or j-th block and has smaller number of integration points.

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.

◆ giveIntegrationDomain()

integrationDomain oofem::BondLink3dBoundary::giveIntegrationDomain ( ) const

inlineoverrideprotectedvirtual

Returns integration domain for receiver, used to initialize integration point over receiver volume. Default behavior is taken from the default interpolation.

Returns: Integration domain of element.

◆ giveInternalForcesVector()

void oofem::BondLink3dBoundary::giveInternalForcesVector	(	FloatArray &	answer,
		TimeStep *	tStep,
		int	useUpdatedGpRecord = 0 )

overridevirtual

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).

◆ giveLocalCoordinateSystem()

int oofem::BondLink3dBoundary::giveLocalCoordinateSystem ( FloatMatrix & answer )

overridevirtual

Returns local coordinate system of receiver Required by material models with ortho- and anisotrophy. Returns a unit vectors of local coordinate system at element stored row-wise. If local system is equal to global one, set answer to empty matrix and return zero value.

Returns: nonzero if answer computed, zero value if answer is empty, i.e. no transformation is necessary.
