Abstract
In their Perspective, Bilde-Sørensen and Schiøtz highlight the report by Chen et al., whose experimental study on the deformation behavior of nanocrystalline aluminum corroborates recent simulations. The study illustrates how the combination of computer simulations and experiment can yield important advances in understanding the atomic-scale properties of materials. As the scale and accuracy of simulations increase, they will be increasingly used to test new materials in "virtual laboratories."
