Detailed Description

This class implements an quad Discrete Kirchhoff Theory (DKT) element. This element is a plate element suitable for thin plates, as the traswerse shear strain energy is neglected. The element has only 12 DOFs (w-displacement and rotations along coordinate axes) in each node The derivation starts by assuming quadratic variations of rotation field (fi_x, fi_y) The Kirchhoff hypothesis is imposed at vertices and in mid side nodes The cubic variation of transwerse displacement is assumed along the edges, there is no need to define interpolation for w on the element. As w varies cubically along the edges, its derivative along the edge varies quadratically as the normal rotation along the edge. This allows to satisfy the Kirchhoff hypothesis along the edge. The rotation along the edge is assumed to vary linearly. This allows to express midside rotations (along and normal to the each edge) as a linear combination of nodal rotations and displacements.

Tasks:

• calculating its B,D,N matrices and dV.

Member Function Documentation

computeBmatrixAt()

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

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).

Computes surface interpolation matrix. Interpolation matrix provide way, how to compute local surface unknowns (nonzero element unknowns on surface) at any integration point of surface, based on local unknowns in surface nodes. Local coordinate system of surface edge and element surface numbering is element dependent. The integration point is specified using two-dimensional iso coordinates, or using area coordinates for triangular surface.

giveDofManDofIDMask()

void oofem::QDKTPlate::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.
