“…The works of Põdra and Andersson (1999a) and Põdra and Andersson (1999b) present a sliding wear algorithm based on the FEM commercial code. On the BEM area, the number of works related with wear is not very ample, the main ones belongs to Sfantos and Aliabadi (2006a), Sfantos and Aliabadi (2006b), Sfantos and Aliabadi (2007) and Lee et al (2009).…”

a b s t r a c tThe present work shows a new numerical treatment for wear simulation on 3D contact and rolling-contact problems. This formulation is based on the boundary element method (BEM) for computing the elastic influence coefficients and on projection functions over the augmented Lagrangian for contact restrictions fulfillment. The constitutive equations of the potential contact zone are Signorini's contact conditions, Coulomb's law of friction and Holm-Archard's law of wear. The proposed methodology is applied to predict wear on different contact and rolling-contact problems. Results are validated with numerical solutions and semi-analytical models presented in the literature. The BEM considers only the degrees of freedom involved on these kind of problems (those on the solids surfaces), reducing the number of unknowns and obtaining a very good approximation on contact tractions using a low number of elements. Together with the formulation, an acceleration strategy is presented allowing to reduce the times of resolution.

“…It is of importance for any technical system with joints subjected to oscillations. Very much attention was paid to fretting in such applications as fretting of tubes in steam generators and heat exchangers 1 2 3 , joints in orthopedics 4 , electrical connectors 5 , and dovetail blade roots of gas turbines 6 7 as well as many others. Depending on particular properties of materials and on loading conditions, fretting wear can lead either to a progressive wear or to some final state in which no further wear occurs.…”

We consider fretting wear due to tangential oscillations of two contacting bodies. For small oscillation amplitudes, the wear occurs only in a circular slip zone at the border of the contact area. With increasing number of cycles, the wear profile tends to a limiting form, in which no further wear occurs. Under assumption of a constant coefficient of friction, the limiting form of the wear profile does not depend on the particular wear criterion and can be calculated analytically. An explicit analytic solution is presented for arbitrary initial shape and illustrated for the cases of parabolic and conical shapes.

“…For practical applications of the above rules, first, the effective one-dimensional MDR-profiles in the initial state have to be determined by using equation (3). In the case of a parabolic form of the indenter f 0 ðrÞ ¼ r 2 =ð2RÞ, the corresponding MDR-transformed profile is g 0 ðxÞ ¼ x 2 =R.…”

We consider fretting wear due to superimposed normal and tangential oscillations of two contacting bodies, one of which is an elastomer with a linear rheology. Similarly to the contact of elastic bodies, at small oscillation amplitudes, the wear occurs only in a circular slip zone at the border of the contact area and the wear profile tends to a limiting form, in which no further wear occurs. It is shown that under assumption of a constant coefficient of friction at the contact interface, the limiting form of the wear profile does depend neither on the particular wear criterion nor on the rheology of the elastomer and can be calculated analytically in a general form. The general calculation procedure and explicit analytic solutions for two initial forms, parabolic and conical, are presented for various combinations of frequencies and phases of normal and tangential oscillations as well as for various linear rheologies of the elastomer.
