Raw data for the paper "A comprehensive model of surface abrasion based on the discrete element method"

This dataset includes the raw data shown in the paper "A comprehensive model of surface abrasion based on the discrete element method" by R.Capozza and K. Hanley. The article describes a new model for abrasion. It simulates the evolution of a surface abraded by a rigid object and describes both the abrasion due to scratching and normal/oblique impact. A group of particles models the surface, characterised by the hardness. When the pressure overcomes a threshold, particles are displaced to account for the change in surface profile. In the case of impact, the abraded volume grows with the velocity and reaches a maximum between 0 and 90◦. In the case of scratching, the dependence of the abraded volume on the normal load is linear in a limited range of loads (Archard’s law) and transitions to a non-linear behaviour with the increase of load. Energy dissipation is naturally included in the model without additional parameters. This conceptually simple approach can easily be extended to model a variety of industrial applications and predict wear patterns under varying scenarios.
