Modeling of polycrystals with gradient crystal plasticity: A comparison of strategies
Artikel i vetenskaplig tidskrift, 2010

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.
