Abstract Crystal plasticity finite element modelling of foil rolling prediction was crucial to validate and improve material models as well as to understand underlying plastic deformation mechanism in grain-scale. The deformation properties of foil rolling based materials depend strongly on the microstructure (grain boundary, slip system and orientation). Annealed single layer crystal copper foils were taken as raw materials, and after the processes of foil rolling was studied by experiment and crystal plasticity finite element simulation. The aim of this study was to model single and multiple slip activation and strain localization behavior of foil rolling of copper single layer crystal by using crystal plasticity finite element simulation, which taking into account the heterogeneous distribution of the shapes, grain boundaries and orientations of the grain. To accurately reproduce the initial grain morphology in the CPFEM simulation without assumptions regarding the sub-surface microstructure, a single layer crystal copper foil was used. In particular, it was shown that the heterogeneous distribution of the grain influences significantly the plastic deformation mechanism of single layer crystal copper foil rolling. The slip activation and deformation at grain boundary were significantly different from the interior and surface grain. A single layer crystal slip was markedly heterogeneous, gives rise to form local slip band and strain localization, with rolling reduction driving strong variations, correctly captured by the model. Remarkable variations of slip activation and plastic strain occur between locations either side of grain boundaries, providing appropriate opportunities for sub-grain and micro-crack nucleation.
