The dependence of the peak forces on the sample Young’s modulus for the parametrical equation of Equation 8 (full line plots) and the corresponding numerical simulations for Tatara’s contact mechanics model (dashed line plots). (a) Asp = 0.9A0 and (b) Asp = 0.7A0. Parameters defined for (a) and (b) are: A0 = 4 nm, Q = 2, k = 0.1 N/m and Rt = 5 nm.
