Abstract: In this study, a novel three-body wear model is introduced to simulate the three-body wear in a block-on-disk test rig with layers of silica sand as abrasive. We aim to simulate the wear depth and the wear intensity when applied loads and velocity are given a priori. The kinematics of the particle layers, the contact stiffness and the friction characteristic have transparent effects on the wear process and are represented by regression functions of applied loads and relative velocity. These functions are incorporated into the modified Fleischer three-body wear equation that represents wear at various discrete points. The wear of the sample and the disk, which is represented by the wear intensity and wear depth, is thereby calculated accumulatively from the wear at these points. Simulation results exhibit good agreement with experimental ones. Therefore, this model allows for a realistic and numerically efficient calculation of wear in three-body contact, and hence a possible wear predictor.

Keywords: three-body abrasive wear; wear simulation; discrete contact elements; mathematical modelling.
