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

answer	Computed result.
mplane	Pointer to microplane object, for which response is computed.
strain	Strain vector.
tStep	Time step.

virtual

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

Parameters

answer	Vector of thermal dilatation coefficients.
gp	Integration point.
tStep	Time step (most models are able to respond only when tStep is current time step).

Reimplemented from oofem::StructuralMaterial.

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.
