Abstract: The present study focuses on the erosion mechanism observed during abrasive water jet (AWJ) machining. An ANSYS/LS-Dyna 3D software-based finite element (FE) model is developed for the representation of the erosion process in a 3D configuration. The proposed FE model's solution, which accounts for the effect of multiple particle impacts on a workpiece made of stainless steel (AISI 304), is obtained using a 16-node cluster system. The influence of impact angle and particle velocity is currently studied, while the material's crater circularity is also evaluated. The results of the present study are found to be in very good agreement with their experimental counterparts.
