Fast High-Resolution Simulation of the Gross Slip Wear of Axially Symmetric Contacts

Abstract

In the present paper, we study the development of wear profile in an axially symmetric contact under conditions of gross slip and assumption of the Reye-Archard wear criterion. Simulations are carried out using the Method of Dimensionality Reduction and a full FEM formulation. The calculation time of the proposed model is several orders lower than that of FEM-based models and allows for much higher spatial resolution.

Wear Analysis of a Heterogeneous Annular Cylinder

“…Both parameters are normalized by the according values of the limiting profile u stat z,max and t stat w . As indicated by Equation (13), wear occurs on all parts of the cylinder. The profile however changes only as long as the product C(r) = p(r)k(r) is not constant.…”

“…The MDR was proposed by Popov and Heß for the fast calculation of various contact problems [9]. Note that it provides not approximation but exact solutions for axisymmetric contacts by mapping of three-dimensional contacts onto one-dimensional contacts, and has been applied to studying on different wear problems, e.g., fretting wear [10] and gross slip wear [11], which were also validated by experiment [12] or by the finite element method [13]. The advantage of the MDR is very fast calculation; the disadvantage is that (for wear problems) it can only be applied to axially-symmetric contact problems.…”

Effect of thickness and boundary conditions on the behavior of viscoelastic layers in sliding contact with wavy profiles

“…The growing interest in polymeric materials, strongly supported by industrial demands, has boosted the scientific effort in such field of materials. The demanding problem of an accurate modelling of the contact behavior has been addressed by analytical approaches [1][2][3][4][5][6][7], numerical sophisticated simulations [8][9][10][11][12][13][14][15] and experimental investigations [16][17][18][19][20]. One of the most common assumptions in contact mechanics is that the contact bodies can be well represented by semi-infinite solids.…”

Limiting shape of profile due to dual-mode fretting wear in contact with an elastomer

“…26 In the paper, 30 the wear process has been simulated and it was confirmed that with increasing number of oscillation cycles the shape of worn profile tends to the limiting form found in Popov. 26 The same procedure as used in Dimaki et al 27 was additionally validated by comparison with finite element simulations in Dimaki et al 28 Thus, the approach of the paper 26 can be considered as validated by at least two independent simulation methods. In the present paper, we will generalize the treatment suggested in the paper 26 to the dual-mode wear (superposition of normal and tangential oscillations) and the case of visco-elastic contact.…”
