...Yeau-Ren Jeng; Shin-Rung Peng The friction coefficient ( μ ) of a contact surface with elliptical asperities is examined at various values of the plasticity index ( ψ ) , the effective radius ratio ( γ ) , the shear-strength-pressure proportionality constant ( c ) , and the dimensionless limiting...

...Yeau-Ren Jeng; Shin-Rung Peng This study investigates the effects of asperity interactions on the mean surface separation and real contact area of rough surfaces containing elliptical asperities with Gaussian and non-Gaussian height distributions. The elastic-plastic contact behavior of surfaces...
