Detailed Description

This class implements a layered cross section in a finite element problem. A cross section is an attribute of a domain. It is usually also attribute of many elements.

The attribute 'propertyDictionary' contains all the properties of a layered cross section, like thickness and width of each layer. The attribute 'layerMaterials' contains an array of Materials corresponding to each layer.

It uses master - slave GaussPoint approach, where master gp has more slaves gp. slave gp represent for each layer material point. It's coordinate sections contains z-coordinate (-1,1) from mid-section. The slaves are manage completely ( created, saved their context.,,,) from this class. Master gp only deletes slaves in destructor.

Tasks:

Returning standard material stiffness matrices (like 3d stress-strain, 2d plane , plate, 3d beam, 2d beam ..) according to current state determined by parameter StressMode by calling material and by possible modifying returned matrix (for example in layered mode approach each layer is asked for 3dMaterialStiffness and this is integrated for example over thickness for plate bending problems).
Returning RealStress state in Gauss point and for given Stress mode.
Returning a properties of cross section like thickness or area.

void oofem::LayeredCrossSection::giveCauchyStresses	(	FloatArray &	answer,

inlineoverridevirtual

Computes the Cauchy stress vector for a given increment of deformation gradient and given integration point. The service should use previously reached equilibrium history variables. Also it should update temporary history variables in status according to newly reached state. The temporary history variables are moved into equilibrium ones after global structure equilibrium has been reached by iteration process. 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.

Todo: should this then be in a multiplicative way? /JB

tStep Current time step (most models are able to respond only when tStep is current time step).

overridevirtual

Returns modified gradient of stress vector, which is used to bring stresses back to yield surface. Method imposes zeros on places, where zero stress occurs. if energetically connected strain is zero, we do not impose zero there, because stress exist and must be taken into account when computing yield function. In such case a problem is assumed to be full 3d with some explicit strain equal to 0. On the other hand, if some stress is imposed to be zero, we understand such case as subspace of 3d case (like a classical plane stress problem, with no tracing of e_z, sigma_z)

Parameters

gp	Integration point.

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
