◆ computeStiffnessMatrix()

void oofem::LIBeam3dBoundary::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.

◆ computeStrainVector()

void oofem::LIBeam3dBoundary::computeStrainVector	(	FloatArray &	answer,

◆ giveDofManDofIDMask()

void oofem::LIBeam3dBoundary::giveDofManDofIDMask	(	int	inode,
		IntArray &	answer ) const

overridevirtual

Returns dofmanager dof mask for node. This mask defines the dofs which are used by element in node. Mask influences the code number ordering for particular node. Code numbers are ordered according to node order and dofs belonging to particular node are ordered according to this mask. If element requests dofs using node mask which are not in node then error is generated. This masking allows node to be shared by different elements with different dofs in same node. Elements local code numbers are extracted from node using this mask. Must be defined by particular element.

Parameters

inode	Mask is computed for local dofmanager with inode number.
answer	Mask for node.

◆ giveInternalForcesVector()

void oofem::LIBeam3dBoundary::giveInternalForcesVector	(	FloatArray &	answer,
		TimeStep *	tStep,
		int	useUpdatedGpRecord = 0 )

overrideprotectedvirtual

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).

Parameters

answer	Contain corresponding integration point value, zero sized if not available.
gp	Integration point to check.
type	Determines the type of internal variable.
tStep	Time step.

Returns: Nonzero if o.k, zero otherwise.

Todo: This should be a common inheritance for all 3d beams (and a similar one for 2D beams) to support all the sensible moment/force tensors.

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)

◆ giveLocalCoordinateSystem()

int oofem::LIBeam3dBoundary::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.
