◆ computeBmatrixAt()

void oofem::LatticeBeam3dBoundary::computeBmatrixAt ( GaussPoint * gp,
FloatMatrix & answer,
int lowerIndx = 1,
int upperIndx = ALL_STRAINS )
inlineoverrideprotectedvirtual

Computes the geometrical matrix of receiver in given integration point. The product of this matrix (assembled at given integration point) and element displacement vector is element strain vector. If lowerIndx and upperIndx parameters are specified, answer is formed only for strains within this interval. This will affects the size of answer.

Parameters
gpIntegration point for which answer is computed.
answerGeometric matrix of receiver.
lowerIndxIf specified, answer is formed only for strain with index equal and greater than lowerIndx. This parameter has default value 1 (answer is formed from first strain).
upperIndxIf specified, answer is formed only for strain with index less and equal than upperIndx. This parameter has default value ALL_STRAINS (answer is formed for all strains).

◆ computeStiffnessMatrix()

void oofem::LatticeBeam3dBoundary::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
answerComputed stiffness matrix (symmetric).
rModeResponse mode.
tStepTime step.

◆ giveDofManDofIDMask()

void oofem::LatticeBeam3dBoundary::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
inodeMask is computed for local dofmanager with inode number.
answerMask for node.

◆ giveInternalForcesVector()

void oofem::LatticeBeam3dBoundary::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
answerInternal nodal forces vector.
tStepTime step.
useUpdatedGpRecordIf 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).
