Grahic Jump Location
The asperity height distribution and radius distribution of the two surfaces, i.e., radius ratio (βiavg) as a function of normalized height (zis)
Grahic Jump Location
Comparison of the deterministic model and the statistical model for the two surfaces in contact with a flat surface (without layer) (a) case 1 and (b) case 2 (see Table 1)
Grahic Jump Location
The comparison between the measurements performed by Sherbiney 11 (a) and the FEM simulation carried out by Tang and Arnell 12 (b) with the calculated results using the present model. (The units along the axis are according to the literature data 1112.)
Grahic Jump Location
Dimensionless separation (d/σ) and dimensionless contact area (At/Anom) as a function of dimensionless load (Ptot/(Et=0*Anom)) for different thicknesses (t) of the lead layer on a flat surface in contact with the surfaces, case 1 and case 2 (see Table 1)
