Microstructurally based cross-slip mechanisms and their effects on dislocation microstructure evolution in fcc crystals (2015, positive): “Over the past two decades, two-dimensional (2D) and three-dimensional (3D) DDD methods have been developed to simulate plastic deformation at the mesoscale in crystalline structures by direct numerical simulations of the collective motion of dislocation ensembles according to physics-based rules [27”
Multiscale modeling of the plasticity in an aluminum single crystal (2009, methodology): “These authors proposed to modify the hardening law of a dislocation based crystal plasticity model (Ohashi, 1994) according to the minimum shear stress needed to emit a dislocation loop into a confined system calculated by DD simulations (Zbib and Diaz de la Rubia, 2002).”
