This paper treats the computational modeling of size dependence in microstructure models of metals. Different gradient crystal plasticity strategies are analyzed and compared. For the numerical implementation, a dual-mixed finite element formulation which is suitable for parallelization is suggested. The paper ends with a representative numerical example for polycrystals. One of the reviewer pointed out that there will be an upcoming paper showing that this model can be recasted in a true work-conjugated formulation.
