... incorporated into a previously developed rough surface contact model to calculate the corresponding interfacial forces. The results were then directly compared to a single Gaussian approximation (ignoring the bimodality) as well as a high-order polynomial curve-fit approximation (encompassing the bimodality...

... are identified that govern the character of the solution. Curve fits are performed to reveal analytical relationships among the dimensionless groups. At extreme values of particular parameters, the curve fits are found to recover the analytical results of the well-known Hertzian and Johnson–Kendall–Roberts...

... coefficient results in higher traction, as expected. However, the point of total traction loss is still at B = 400 for all μ s values. The data is best represented by the following mixed polynomial curve fit: (24) Δ N ¯ = − 3.24 × 10 − 2 + 1.93 μ s − 9.26...
