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).

IRResultType oofem::RCSDMaterial::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

ir	Input record to initialize from.

Returns: IRResultType
