Molecular Dynamics Simulation for Abrasive Processes

Abstract Until today several applications of Molecular Dynamics in mechanical engineering fields have been carried-out, focusing on the simulation of indentation tests or cutting processes. In this paper the application of Molecular Dynamics for Abrasive Processes is discussed and the first results from simulations are presented which are targeting on the pile-up phenomenon in abrasive machining. Particularly the differences and necessities in contrast to the simulation of cutting processes are taken into account. Some principal problems and components of the model representation as well as applied techniques in indentation and cutting simulations are discussed in more detail. Finally new methods to improve the model representation and to enhance the calculation speed for large models are given.
