Abrasion is one of the dominant source for the damage of soil engaging tools such as tines, ploughshares, separators etc. Since the conventional abrasion analysis relies on the posterior groove-ridge investigation from the worn surface profile, this study presents a numerical approach to predict the abrasive wear behaviors including the micro-cutting and micro-ploughing. A Finite Element Model (FEM) has been developed to identify these mechanisms. Modeling techniques representing local plastic deformation from microploughing and material removal from micro-cutting were implemented. A comparison between basic von Mises plasticity model and a strain-based damage model namely Modified Bai Wierzbicki (MBW) was discussed. The material characterization and its model calibration were included. The grooveridge ratio from single-asperity scratch test experimental results were used as a benchmark parameter.
