Atomistic Simulations of Scratching and Cutting of Surfaces

Using classical molecular dynamics simulation we shall investigate the dynamic contact of two solids. For the materials steel (iron) and titanium, the processes of indentation, scratching and cutting will be simulated. In particular the following processes will be characterized: the influence of rough and nanostructured surfac-es on the machining process, processes occurring in polycrystalline materials, cyclic machining, and the mechanisms underlying the lapping process.
