Detailed Description

Class implementing "simple" cross section model in finite element problem.

A cross section is an attribute of a domain. It is usually also attribute of many elements.

The simple cross section implementation does not perform any integration over cross-section volume, it represents a cross section model, where the whole cross section model is represented by single integration point. and therefore all requests for characteristic contributions (stiffness) and for real stress computations are simply passed to parent StructuralCrossSection class, which invokes corresponding material mode services. Please note, that it is assumed that material model will support these material modes and provide corresponding services for characteristic components and stress evaluation. For description, how to incorporate more elaborate models of cross section, please read base CrossSection documentation.

The overloaded methods giveFullCharacteristicVector and giveFullCharacteristicVector add some additional support for integrated cross section models - _3dShell, _3dBeam, _2dPlate and _2dBeam.

This class also reads into its property dictionary necessary geometric cross section characteristics, which are requested by particular material models. These parameters can be requested using get service and include those defined by CrossSectionProperty.

Elements should always pass their requests to their cross section model, which performs necessary integration over its volume and invokes necessary material services for corresponding material model defined for given integration point.

Parameters

answer	Contains the Cauchy stress.
gp	Integration point.
reducedFIncrement	Increment of the deformation gradient vector in reduced form.

void oofem::SimpleCrossSection::giveGeneralizedStress_Beam2d ( FloatArray &  answer, GaussPoint *  gp, const FloatArray &  generalizedStrain, TimeStep *  tStep  )

Parameters

answer	Contains result.
gp	Integration point.
generalizedStrain	Strain vector in reduced generalized form.
tStep	Current time step (most models are able to respond only when tStep is current time step).

Note: (by bp): This assumes that the behaviour is elastic there exist a nuumber of nonlinear integral material models for beams defined directly in terms of integral forces and moments and corresponding deformations and curvatures. This would require to implement support at material model level. Mikael: That would not be a continuum material model, but it would highly depend on the cross-section shape, thus, it should be a special cross-section model instead. This cross-section assumes you can split the response into inertia moments and pure material response. This is only possible for a constant, elastic response (i.e. elastic). Therefore, this cross-section may only be allowed to give the elastic response.

Note: (by bp): This assumes that the behaviour is elastic there exist a nuumber of nonlinear integral material models for beams/plates/shells defined directly in terms of integral forces and moments and corresponding deformations and curvatures. This would require to implement support at material model level. Mikael: See earlier response to comment

Computes the material stiffness matrix dCde of receiver in a given integration point, respecting its history.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result. Elements should always pass their requests to their cross section model, which performs necessary integration over its volume and invokes necessary material services for corresponding material model defined for given integration point.

Parameters

answer	Contains result.

int oofem::SimpleCrossSection::packUnknowns ( DataStream &  buff, TimeStep *  tStep, GaussPoint *  ip  )

virtual

Pack all necessary data of integration point (according to element parallel_mode) into given communication buffer.

The corresponding material model service for particular integration point is invoked. The nature of packed data is material model dependent. Typically, for material of "local" response (response depends only on integration point local state) no data are exchanged. For "nonlocal" constitutive models the send/receive of local values which undergo averaging is performed between local and corresponding remote elements.

Parameters

buff	Communication buffer.
tStep	Solution step.
ip	Integration point.

Returns

Nonzero if successful.
