Detailed Description

This class implements a linear tetrahedral four-node finite element. Each node has 3 degrees of freedom. This element is used for 3D RVE analyses with Periodic Boundary Conditions. 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. MACROSCOPIC INPUT: DEFORMATION GRADIENT TENSOR (3D, 9 COMPONENTS: Exx Exy Exz Eyx Eyy Eyz Ezx Ezy Ezz)

◆ computeBHmatrixAt()

void oofem::LTRSpaceBoundary::computeBHmatrixAt	(	GaussPoint *	gp,

overrideprotectedvirtual

Computes a matrix which, multiplied by the column matrix of nodal displacements, gives the displacement gradient stored by columns. The components of this matrix are derivatives of the shape functions, but they are arranged in a somewhat different way from the usual B matrix.

Parameters

gp	Integration point.
answer	BF matrix at this point.

void oofem::LTRSpaceBoundary::computeBmatrixAt	(	GaussPoint *	gp,

		int	lowerIndx = 1,

overrideprotectedvirtual

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

gp	Integration point for which answer is computed.
answer	Geometric matrix of receiver.
lowerIndx	If 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).
upperIndx	If 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::LTRSpaceBoundary::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.

◆ giveDofManDofIDMask()

void oofem::LTRSpaceBoundary::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::LTRSpaceBoundary::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).

◆ giveIPValue()

int oofem::LTRSpaceBoundary::giveIPValue	(	FloatArray &	answer,
		GaussPoint *	gp,

overrideprotectedvirtual

Returns the integration point corresponding value in full form.

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: 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)
