A Computational Wear Model of the Oblique Impact of a Ball on a Flat Plate

Many wearing processes are a result of the oblique impacts. 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.
