Member Function Documentation

◆ computeStiffnessMatrix()

void oofem::QPlaneStress2dSlip::computeStiffnessMatrix	(	FloatMatrix &	answer,
		MatResponseMode	rMode,
		TimeStep *	tStep )

overridevirtual

Computes the stiffness matrix of receiver. The response is evaluated using \( \int B_{\mathrm{H}}^{\mathrm{T}} D B_{\mathrm{H}} \;\mathrm{d}v \), where \( B_{\mathrm{H}} \) is the B-matrix which produces the displacement gradient vector \( H_{\mathrm{V}} \) when multiplied with the solution vector a. Reduced integration are taken into account.

Parameters

answer	Computed stiffness matrix.
rMode	Response mode.
tStep	Time step.

Todo: We probably need overloaded function (like above) here as well.

Todo: Verify that it works with large deformations

◆ giveDofManDofIDMask()

void oofem::QPlaneStress2dSlip::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::QPlaneStress2dSlip::giveInternalForcesVector	(	FloatArray &	answer,

overridevirtual

Evaluates nodal representation of real internal forces. Necessary transformations are taken into account.

Todo: what is meant?

Parameters

answer	Equivalent nodal forces vector.
tStep	Time step
useUpdatedGpRecord	If equal to zero, the stresses in integration points are computed (slow but safe).

Todo: Is this really what we should do for inactive elements?

Todo: This is actaully inefficient since it constructs B and twice and collects the nodal unknowns over and over.

Todo: is this check really necessary?

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)
