void oofem::RankineMatNl::givePlaneStressStiffMtrx ( FloatMatrix answer,

virtual

Method for computing plane stress stiffness matrix of receiver.

Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to plane stress stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix.

Parameters
answerStiffness matrix.
mmodeMaterial response mode.
gpIntegration point, which load history is used.
tStepTime step (most models are able to respond only when tStep is current time step).

int oofem::RankineMatNl::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 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
buffCommunication buffer.
tStepSolution step.
ipIntegration point.

void oofem::RankineMatNl::updateBeforeNonlocAverage ( const FloatArray strainVector,
GaussPoint gp,
TimeStep tStep 
)
virtual

Declares the service updating local variables in given integration points, which take part in nonlocal average process.

Because value of single integration point influences nonlocal variables in several near integration points, it is suitable to compute these variables only once. These should be stored in integration point associated statuses. The implementation is left on derived classes. Provide material local strain increment - as is provided to computeRealStresVector. This allows to update internal vars to be averaged to new state

Parameters
strainVectorTotal strain vector in given integration point.
gpIntegration point to update.
tStepSolution step indicating time of update.
