The dynamical evolution of simulated disks, resulting from perturbations by central bars and spiral structure. Three topics: (i) velocity moving groups (the u-v plane) in the solar neighborhood, (ii) the contribution of radial migration to disk thickening, and (iii) the formation of different types of disk outskirts as the result of angular momentum transfer. Possible tests with forthcoming surveys will be discussed.
