Microplane mplane,
const FloatArray strain,
TimeStep tStep 
)
virtual

Computes real stress vector on given microplane (the meaning of values depends on particular implementation, e.g, can contain volumetric, deviatoric normal stresses and shear stresses on microplane) for given increment of microplane strains.

Parameters
answerComputed result.
mplanePointer to microplane object, for which response is computed.
strainStrain vector.
tStepTime step.

Implements oofem::MicroplaneMaterial.

void oofem::M4Material::giveThermalDilatationVector ( FloatArray answer,
GaussPoint gp,
TimeStep tStep 
)
virtual

Returns a vector of coefficients of thermal dilatation in direction of each material principal (local) axis.

Parameters
answerVector of thermal dilatation coefficients.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).

IRResultType oofem::M4Material::initializeFrom ( InputRecord ir)
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.

Parameters
irInput record to initialize from.
Returns
