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.

Implemented in oofem::MDM, oofem::M1Material, and oofem::M4Material.

void oofem::MicroplaneMaterial::initializeData ( int  numberOfMicroplanes)

Initializes internal data (integration weights, microplane normals and computes projection tensors).

Parameters
numberOfMicroplanesNumber of required microplanes.

Reimplemented in oofem::MDM.

IRResultType oofem::MicroplaneMaterial::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

Returns

void oofem::MicroplaneMaterial::initTempStatus ( GaussPoint gp)
protectedvirtual

Initializes temporary variables stored in integration point status at the beginning of new time step.

Temporary history variables (they describe state of material during solution of time step) are initialized according to history variables, which describe state corresponding to previous equilibrium solution. Default implementation simply extracts status from integration point and calls its initTempStatus method.
