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.

Declares the service updating local variables in given integration points, which take part in nonlocal average process. Because value of single integration point influences nonlocal variables in several near integration points, it is suitable to compute these variables only once. These should be stored in integration point associated statuses. The implementation is left on derived classes. Provide material local strain increment - as is provided to computeRealStresVector. This allows to update internal vars to be averaged to new state
