Knowing the effective impact parameters on the wear mechanism would be helpful to have the more reliable designs. The H-DD (Hertz-Di Maio Di Renzo) nonlinear model of impact followed by the time increment procedure is used to simulate the impact process of a ball on a flat plate. Restitution parameters are extracted and compared with the experimental data to ensure the accuracy of the impact model. The constant parameters of a wear equation are determined by comparing the results with the experimental data. The results obtained suggest that this simulation method could be used as a predictive way to study the practical design problems and to explain some phenomena associated with impact erosion.
