摘要：The abrasive water jet (AWJ) is a modern material machining method. In this study, an AWJ-material interaction model that considers the shape, interaction and fragmentation of abrasive particles was developed based on the coupled smoothed particle hydrodynamics (SPH) and finite element method (FEM). Firstly, the theoretical model of jet impact force is utilized to verify the precision of the numerical model, and error of the jet impact force between the numerical and theoretical model is 6.87 %. Then, the mean AWJ impact force, fluctuation degree of AWJ impact force and water impact force ratio during the AWJ material interaction process are investigated. Finally, the effects of the abrasive particle radius, abrasive mass concentration, impact velocity, impact angle and target shape on the AWJ impact force characteristics are revealed. The results deepen the understanding of the AWJ-material interaction process and are beneficial for improving the energy efficiency of the AWJ operation. ? 2024
