“…We emphasize that the asymptotic formulas (19) and (20) differ from the approximations derived in [13]. In fact, the results obtained by Komogortsev [13] follow from formulas (19) and (20) by substituting the approximation for u 1 (x 0 ) obtained by Galerkin's method in terms of the Chebyshev polynomials of the first kind. It is interesting that the eigenvalues k m do not depend on the elastic layer's thickness.…”

“…Analytical approach for wear contact problems with fixed contact area was developed by Galin [11], and lately extended in a number of publications [12,13]. Applying an optimal control approach [14] recently developed to study the asymptotic behavior of elasto-viscoplastic structures, Peigney [15] has solved the problem of determining the asymptotic state reached by an elastic half-plane subjected to wear and submitted to a normal and tangential loading by a cyclically moving rigid indenter with the prescribed vertical displacement.…”

The article presents asymptotic modeling of the running-in wear process with fixed contact zone under a prescribed constant normal load or an imposed contact displacement. The wear contact problem is formulated within the framework of the two-dimensional theory of elasticity in conjunction with Archard's law of wear. The running-in process is considered at the macro-scale level, while the micro-processes associated with roughness changes, tribomaterial evolution, and microstructural alteration in the subsurface layers as a first approximation are neglected. The setting of the steady-state regime for the macro-contact pressure evolution is chosen as the criterion to characterize the completion of running-in. Simple closed-form approximations are derived for the running-in period and running-in sliding distance. The obtained results can be used for estimating the running-in period in wear processes where the evolution of the macro-shape deviations at the contact interface plays a dominant role.

“…It was Galin (1976) who first considered a two-dimensional wear contact problem with a constant area and applied the method of variables separation. Galin's method was further developed by Aleksandrov et al (1978) and Komogortsev (1985) and extended to threedimensional wear contact problems (Galin and Goriacheva, 1977;Kovalenko, 1985).…”

Fretting is a special type of wear, which appears at the contact interface between two solids subjected to constant normal load and periodic tangential forces. Although most studies on fretting have been executed experimentally, some approaches for simulating fretting wear have also been introduced during the last decades. In particular, fretting wear analysis is concerned with the evolution of the surface profiles of the contacting bodies due to wear, and its modeling was executed using numerical, finite-element, semi-analytical, and analytical methods, including the method of dimensionality reduction. In the present review we discuss recent analytical results on fretting wear contact geometry adaptation.
