A 3-D finite element model of abrasion process based on a CEL (Coupled Eulerian-Lagrangian) approach was developed. A scratch test on elastic-perfectly plastic materials with a pyramidal indenter was simulated. The influence of the interfacial friction coefficient f, the geometric parameters of the indenter and the cutting conditions on the overall friction coefficient μ were studied. Subsequently, the finite element simulation results were compared with an analytical model. It was found that the µ increases linearly with the friction coefficient f and the attack angle of grit β. The FE model results present a good agreement with the analytical model results.
