... 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...

... of study, more investigation should be conducted in this area to identify the proper variables and the true statistical distribution for all rolling bearing constructions. Rolling Element Bearing Fatigue Life Reliability Figure 5 shows the current data and three-parameter Weibull curve fit...

... representation of a web moving over a roller at the onset of sliding For all cases, curve-fits were obtained using I = 1 , 2 and 3 for Δ N ¯ as a function of B . This curve fitting is conducted for each of the 25 values of the second variable V 2 . This gives 25...
