Jump-off and jump-to contact. Strong adhesion combined with soft materials may cause sudden jump-off or jump-to contact, see e.g. [8] and [56]. In that case the (de-)bonding process inherently becomes physically unstable, and the assumption of quasi-static conditions (as considered in this work) is not valid anymore.
Eqs. (2), (3), (3a), (3b), (4) were originally proposed based on empirical approaches.
