Detailed Description

Abstract base class for all "structural" finite elements. It declares common interface provided by all derived elements. The implementation of these services is partly left on derived classes, some general services are implemented here generally (But they can be overload by more efficient element implementation). The general implementation provided here is intended for both linear and nonlinear computations. At this level, only material model nonlinearities are taken into account. If particular element type will participate in geometrically nonlinear computations, it should be derived from derived NLStructuralElement class, which provide support for this cases.

The basic data of an element are the numbers of its 'numberOfNodes' nodes, stored in 'nodeArray', of its 'material', of its body loads (eg, the dead weight) stored in 'loadArray'. These data are obtained from the domain. The element contains logical reference to Volume object ( which stores material,geometrical characteristics, integration points, state of material and so on) The calculated data of an element are its 'massMatrix', its 'stiffnessMatrix' its 'locationArray'. Since the load vector is recalculated at every time step, it is not given the status of attribute.

Tasks:

• Obtaining its basic data, the element reads in the data file the number of these objects, then obtains the data from the domain (methods 'giveNode', 'giveMaterial',etc).
• Calculating its contribution to the problem : Calculating its mass matrix M, its stiffness matrix K, its load vector f, its location array. Calculating its contribution to the LHS and RHS of the linear system, using Static,Newmark,etc, formula. These contributions are usually combinations of M,K,f.
• Performing end-of-step operations; Calculating the strains and stresses at its Gauss points.
• Printing its output in the data file and updating itself.

checkConsistency()

int oofem::StructuralElement::checkConsistency ( void )

overridevirtual

Performs consistency check. This method is called at startup for all elements in particular domain. This method is intended to check data compatibility. Particular element types should test if compatible material and crossSection both with required capabilities are specified. Derived classes should provide their own analysis specific tests. Some printed input if incompatibility is found should be provided (error or warning member functions). Method can be also used to initialize some variables, since this is invoked after all domain components are instanciated.

Returns

Zero value if check fail, otherwise nonzero.

computeBmatrixAt()

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

pure virtual

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).

computeConsistentMassMatrix()

void oofem::StructuralElement::computeConsistentMassMatrix ( FloatMatrix & answer, TimeStep * tStep, double & mass, const double * ipDensity = NULL )

virtual

Computes consistent mass matrix of receiver using numerical integration over element volume. Mass matrix is computed as \( M = \int_V N^{\mathrm{T}} \rho N dV \), where \( N \) is displacement approximation matrix. The number of necessary integration points is determined using this->giveNumberOfIPForMassMtrxIntegration service. Only selected degrees of freedom participate in integration of mass matrix. This is described using dof mass integration mask. This mask is obtained from this->giveMassMtrxIntegrationgMask service. The nonzero mask value at i-th position indicates that i-th element DOF participates in mass matrix computation. The result is in element local coordinate system.

Parameters

answer	Mass matrix.
tStep	Time step.
mass	Total mass of receiver.

computeStiffnessMatrix()

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

virtual

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.

giveInternalForcesVector()

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

virtual

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).

updateBeforeNonlocalAverage()

void oofem::StructuralElement::updateBeforeNonlocalAverage ( TimeStep * tStep )

overridevirtual

Updates internal element state (in all integration points of receiver) before nonlocal averaging takes place. Used by so nonlocal materials, because their response in particular point depends not only on state in this point, but depends also on state in point's neighborhood. Nonlocal quantity is computed as nonlocal average of local quantities. Therefore, before updating integration point state depending on nonlocal quantity (or quantities), local quantities in all integration points must be updated in advance. This function updates local quantities of material model using updateBeforeNonlocalAverage member function of structural nonlocal material class.

Parameters

tStep

Time step.

updateInternalState()

void oofem::StructuralElement::updateInternalState ( TimeStep * tStep )

overridevirtual

Updates element state after equilibrium in time step has been reached. Default implementation updates all integration rules defined by integrationRulesArray member variable. Doing this, all integration points and their material statuses are updated also. All temporary history variables, which now describe equilibrium state are copied into equilibrium ones. The existing internal state is used for update.

Parameters

tStep

Time step for newly reached state.
