Calculation of the transient adhesion F′ad. (a) plot of P/Pc vs. δ/δc in Hertz (marked 1) and JKR theory (marked 2)37 (Permitted reprint from ‘Myshkin, N. K., Petrokovets, M. I. and Kovalev, A. V. Tribol. Internat. 38, 910–21 (2005)’); (b) The CCD camera image of the contact area; (c) change of contact radius for three types of situations (OSD and TSD with first detaching displacement = 110 and 175 μm), measuring force during the one-step detachment and numerical fitting force-time curve.
