◆ giveRealStressVector()

void oofem::FRCFCMNL::giveRealStressVector ( FloatArray & answer,
GaussPoint * gp,

overridevirtual

Computes the real stress vector for given total strain and integration point. The total strain is defined as strain computed directly from displacement field at given time. The stress independent parts (temperature, eigenstrains) are subtracted in constitutive driver. 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.

Parameters
answerStress vector in reduced form. For large deformations it is treated as the second Piola-Kirchoff stress.
gpIntegration point.
reducedStrainStrain vector in reduced form. For large deformations it is treated as the Green-Lagrange strain.
tStepCurrent time step (most models are able to respond only when tStep is current time step).
Todo

◆ initializeFrom()

void oofem::FRCFCMNL::initializeFrom ( InputRecord & ir)
overridevirtual

Initializes receiver according to object description stored in input record. This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record. Note that initializeFrom may be called mutiple times.

Parameters
irInput record to initialize from.
priorityPriority of the input record. This is used to determine the order of initialization

◆ updateBeforeNonlocAverage()

void oofem::FRCFCMNL::updateBeforeNonlocAverage ( const FloatArray & strainVector,
GaussPoint * gp,
TimeStep * tStep ) const
inlineoverridevirtual

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.

Implements oofem::StructuralNonlocalMaterialExtensionInterface.
