Creates new copy of associated status and inserts it into given integration point.

Parameters:
gpIntegration point where newly created status will be stored.
Returns:
Reference to new status.

Reimplemented from oofem::Material.

Definition at line 146 of file hyperelasticmaterial.C.

References oofem::FEMComponent::giveDomain().

Computes full 3d material stiffness matrix at given integration point, time, respecting load history in integration point.

Parameters:
answerComputed results.
modeMaterial response mode.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).

void oofem::HyperElasticMaterial::giveRealStressVector_3d ( FloatArray answer,
GaussPoint gp,
const FloatArray reducedE,
TimeStep tStep 
) [virtual]

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.

IR_GIVE_FIELD
IR_GIVE_OPTIONAL_FIELD
Parameters:
irInput record to initialize from.
Returns:
IRResultType
