“…The main idea of how adhesion determines the process of wear was put forward by Rabinowicz in 1958 [7]. He assumed that the process of wear is governed by the interplay of elastic energy stored in a medium and the work of adhesion needed to separate two parts of a body-just as suggested by Griffith in his theory of crack propagation [8].…”

“…The initial idea formulated by Rabinowicz is very vague [7]. Following his experimental findings, he never speaks directly about wear particle formation but about two related processes-the material transfer from one body to the other one and the subsequent process of formation of loose particles and illustrates it by a sketch reproduced in Fig.…”

“…He was a practitioner and always proceeded from empirical observations and not from theoretical models. His work inspired many subsequent studies of this two-stage wear process, e.g., the experimental study [15], which appeared shortly after the paper [7] of Rabinowicz.…”

“…Since, after the loosing contact, only residual stresses remain in the fragment, Rabinowicz assumes that the elastic energy associated with these stresses is only around 0.1 (square of the Poissonnumber) of the maximum energy, so that the fragments will detach from the surface if this energy is sufficient for creating new surfaces with the area A of the Fig. 2 Illustration of the formation of a "wear fragment" during contact and after losing contact [7]. …”

60 years of Rabinowicz’ criterion for adhesive wear

60 years ago, in 1958, Ernest Rabinowicz published a 5 page paper titled "The effect of size on the looseness of wear fragments" where he suggested a criterion determining the minimum size of wear particles. The criterion of Rabinowicz is based on the consideration of the interplay of elastic energy stored in "asperities" and the work of separation needed for detaching a wear particle. He was probably the first researcher who explicitly emphasized the role of adhesion in friction and wear. In a recent paper in Nature Communications, Aghababaei, Warner and Molinari confirmed the criterion of Rabinowicz by means of quasi-molecular dynamics and illustrated the exact mechanism of the transition from plastic smoothing to formation of wear debris. This latter paper promoted the criterion of Rabinowicz to a new paradigm for current studies of adhesive wear. The size arguments of Rabinowicz can be applied in the same form also to many other problems, such as brittle-ductile transition during indentation, cutting of materials or ultimate strength of nano-composites.

“…One of the interesting ideas for adhesive wear (one of the most prevalent types of wear) was suggested in 1958 by Rabinowicz [13] in Wear and was later forgotten (the paper has 12 citations in Google Scholar, even worse than Reye's paper [10]), distinguishing the regimes of plastic smoothing and the formation of wear particles in a contact of homogeneous sliding bodies. Its summary says that "whether a fragment transferred during sliding comes off as a loose wear particle is shown to depend on whether its elastic energy exceeds the surface energy at its point of attachment.…”

Methods of particles are now recognized as an effective tool for numerical modeling of dynamic mechanical and coupled processes in solids and liquids. This chapter is devoted to a brief review of recent advances in the development of the popular particle-based discrete element method (DEM). DEM is conventionally considered as a highly specialized technique for modeling the flow of granular media and the fracture of brittle materials at micro- and mesoscopic scales. However, in the last decade, great progress has been made in the development of the formalism of this method. It is largely associated with the works of the scientific group of Professor S. G. Psakhie. The most important achievement of this group is a generalized formulation of the method of homogeneously deformable discrete elements. In the chapter, we describe keystones of this implementation of DEM and a universal approach that allows one to apply various rheological models of materials (including coupled models of porous fluid-saturated solids) to a discrete element. The new formalism makes possible qualitative expansion of the scope of application of the particle-based discrete element technique to materials with various rheological properties and to the range of considered scales form microscopic to macroscopic. The capabilities of this method are especially in demand in the study of the features of contact interaction of materials. To demonstrate these capabilities, we briefly review two recent applications concerning (a) the effect of adhesive interaction on the regime of wear of surface asperities under tangential contact of bodies and (b) the nonmonotonic dependence of the stress concentration in the neck of the human femur on the dynamics of hip joint contact loading.
