Erosion by the abrasives was regarded as the main mechanism in watejet machining.Several widely used erosive wear model and their erosion mechanisms were reviewed,the applications of finite element method in studying abrasive erosive wear were summarized.Steinberg-Guinan model were selected as the target material constitutive model,the numerical model of garnet particle impacting the stainless steel was designed by using APDL,and the erosion process was simulated by using LS-DYNA code.By comparing the simul...
