void oofem::B3SolidMaterial::giveRealStressVector	(	FloatArray &	answer,

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

answer	Stress vector in reduced form. For large deformations it is treated as the second Piola-Kirchoff stress.
gp	Integration point.
reducedStrain	Strain vector in reduced form. For large deformations it is treated as the Green-Lagrange strain.
tStep	Current time step (most models are able to respond only when tStep is current time step).

Todo: Move this to StructuralCrossSection ?

Computes, for the given integration point, the strain vector induced by stress-independent shrinkage.
