“…Thus, the wear rate decreases [9]. When applied in the numerical simulation, with the consideration of the formation of the third bodies, the simulated results agree better with the measured results [10].…”

To connect terminals in a cyber-physical system, large quantities of electrical contacts are used. In order to guarantee a high reliability of the system, the lifetime of the electrical contacts should be very long. Thus, it is of great importance to understand the failure mechanism and then to predict the lifetime of the electrical contacts. For the applications under high thermal and/or mechanical loads, noble plating is a good choice, considering its inertness to oxidation. For noble plating, one of the most critical failure mechanisms is the fretting wear. Wear debris generated in the contact area, acting as the third bodies, will greatly influence the further wear behavior and electrical performance. In this study, the state of the art regarding third bodies is firstly reviewed, and then the influence of the third bodies on the wear and electrical performance is investigated, from the aspects of lifetime and the element distributions in contact area. Finally, an example of prediction of the wear of noble plating is shown with the consideration of the third bodies. Based on this study, by involving the third bodies, the wear of noble plating can be predicted with a higher accuracy.

“…This is a problem, because, as shown above, wear -to a large extent-controls the crack paths. Recent works from Arnaud et al [27,28] and other, such as [29][30][31][32][33][34], suggest that it might be possible to simulate crack face wear, including the effect of a third body layer (oxidized debris), and this would certainly be very useful.…”

Mode I + II fatigue crack growth tests are run, following sequential or pseudo-sequential loading paths, representative of those computed for "squat type" cracks in rails. Stereo DIC provides the near-tip displacements, from which ∆K ef f ective I and ∆K ef f ective II are derived. Compression while shearing extends coplanar growth, by slowing down the wear-induced rise of the effective mode mixity ratio, up to the critical value for which bifurcation occurs. The consideration of plasticity and contact and friction stresses improves crack paths predictions, compared to the maximum tangential stress criterion. The coplanar crack growth rate correlates well with a combination of ∆K ef f ective I and ∆K ef f ective II .

“…For describing the evolution of the debris layer, the dynamic volume fraction of ejected particles was considered, related to the accumulation of trapped debris volume. A finite element model was developed for simulating a fretting wear profile [92]. The model considered the presence of a third body layer evolving over fretting time.…”

This article reviews fretting wear damage in industries and in the contact mechanics of coated systems. Micro-slip motion resulting in fretting damage is discussed along with major experimental factors. The experimental factors, including normal force, relative displacement, frequency and medium influence are directly compared. Industrial solutions to reduce fretting damages are then discussed. The contact mechanics of a coated system are reviewed to quantify stress states in a coating layer and the substrate. Finally, a literature review on simulation for fretting is carried out. This review study provides useful methods and practical solutions to minimize fretting wear damage.
