“…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 .

“…[40][41] In addition, the existence of carbon spheres between contact surfaces during boundary and mixed lubrication regimes may possibly result in rolling motion where the system act as ball bearing on the nanometer scale. 42 The ability of carbon spheres to maintain their spherical morphology even after going under extreme boundary lubrication conditions supports their rolling motion as the lubricating mechanism.…”

Ultrasmooth submicrometer carbon spheres are demonstrated as an efficient additive for improving the tribological performance of lubricating oils. Carbon spheres with ultrasmooth surfaces are fabricated by ultrasound assisted polymerization of resorcinol and formaldehyde followed by controlled heat treatment. The tribological behavior of the new lubricant mixture is investigated in the boundary and mixed lubrication regimes using a pin-on-disk apparatus and cylinder-on-disk tribometer, respectively. The new lubricant composition containing 3 wt % carbon spheres suspended in a reference SAE 5W30 engine oil exhibited a substantial reduction in friction and wear (10-25%) compared to the neat oil, without change in the viscosity. Microscopic and spectroscopic investigation of the carbon spheres after the tribological experiments illustrated their excellent mechanical and chemical stability. The significantly better tribological performance of the hybrid lubricant is attributed to the perfectly spherical shape and ultrasmooth surface of carbon sphere additive filling the gap between surfaces and acting as a nanoscale ball bearing.

“…The comparisons between BEM method and FE method and analytical models presented in literature have a good agreement. Leonard et al [Leonard, Ghosh, Sadeghi et al (2014)] presented a combined finite-discrete element method to modeling fretting wear based on Archerd wear model. The FEA is used to calculate the internal stresses of the contacting bodies, and discrete element method is employed to determine the interaction between the bodies.…”

“…The FEA is used to calculate the internal stresses of the contacting bodies, and discrete element method is employed to determine the interaction between the bodies. In addition, this method is applied to fretting wear model taking into account the effect of the third body [Leonard, Ghosh, Sadeghi et al (2014)]. In this model, FEM was employed for the calculation of substrate bodies, while the debris and contact interactions between debris and substrates were simulated by the discrete element method.…”

Fretting wear is a material damage in contact surfaces due to micro relative displacement between them. It causes some general problems in industrial applications, such as loosening of fasteners or sticking in components supposed to move relative to each other. Fretting wear is a complicated problem involving material properties of tribosystem and working conditions of them. Due to these various factors, researchers have studied the process of fretting wear by experiments and numerical modelling methods. This paper reviews recent literature on the numerical modelling method of fretting wear. After a briefly introduction on the mechanism of fretting wear, numerical models, which are critical issues for fretting wear modelling, are reviewed. The paper is concluded by highlighting possible research topics for future work.
