Solid particle erosion is affected by many factors such as the impact velocity, the impact angle, the particle size, mechanical properties of the particle and the target. The computer simulation is effective to clarify the erosion mechanism. However, the simulation of erosion is troublesome, because the local surface roughness continuously changes during the process. In this paper, the Extended Distinct Element Method (EDEM) was applied to simulate solid particle erosion. The EDEM is a kind of the mesh-less method and it seems to be effective to simulate a dynamic process like erosion by the EDEM By obtaining the numerical results, the effectiveness of the EDEM for solid particle erosion was examined. The influence of the impact angle of solid particles on erosion was also shown.
