Investigation of surface damage of ductile materials caused by rotating particles

The influence of rotating particles on surface damage should be considered to improve the accuracy of erosion prediction. In the present study, numerical simulations were carried out to investigate the wear morphology and stress distribution of a target material subjected to rotating particle impacts. A new experimental method was established to validate the model. The model was then used to study the influence of rotating particle impacts at different impact velocities and angles on wear behavior of the material. Correlation between the severity impact wear and particle rotation was observed and quantified. The results show that rotation of solid particles impacting a material can significantly affect the magnitude and pattern of impact wear. Particles with a forward spin were found to promote forward movement of the material surface, whereas particles with a backward spin contributed to vertical deformation of the material. Finally, impact wear profiles produced by different particles with different rotation modes were compared. These results provide insights into the damage mechanism of rotating particles and a theoretical basis for further investigations.
