In this presentation, a recent work  on a fast nonlinear homogenization method for simple microstructures is revised. The degrees of freedom of the approach are defined on shear bands. Moreover, the number of degrees of freedom as well as the number of stress computations is very small compared to related finite element (FE) computations making the method fast. The predictions of the computational method are validated by FE-simulations. As a new aspect, the overall algorithmic tangent moduli of the method are derived for the first time.
