Predicting three-body abrasive wear using Monte Carlo methods

Predicting wear of materials under three-body abrasion is a challenging project, since three-body abrasion is more complicated than two-body abrasion. In this paper, a Monte Carlo model for simulating plastic deformation wear rate, i.e. low-cycle fatigue wear rate, is proposed. The Manson-Coffin formula and the Palmgrom-Miner linear accumulated-damage principle were used in the model as well as the Monte Carlo method. This makes the model much more accurate for the wear prediction. In order to compare the computer simulation data with wear experiments, three-body abrasion experiments using spherical abrasive particles were carried out which showed a good agreement with the computer simulation results.
