Cantor Set Surface Parameters (cont’d)
Lo and ho determined using relation between r.m.s. height and topothesy (Feder, 1988).
fx and fz are determined using relation between linear contact area A and displacement u (obtained using volume conservation of Cantor set surface compression).
Using the statistical properties of a self-affine fractal set, the parameter s can be related to D, fx and fz as (Majumdar, 1996)
