Abstract

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.
