• , the tape will tend to spontaneously detach from the substrate. In this case, an external force is necessary to avoid spontaneous detachment and make the tape adhering to the substrate. Keywords: adhesion; double-peeling; energy release rate; peeling of pre-tensioned tape; Introduction The

• , is Equilibrium requires the stationarity of the total energy Utot, i.e., according to the Griffith criterion where Δγ is the Dupré energy of adhesion [38], and G is the energy release rate at the crack tip, defined as when the external load P is given. In Equation 5 S is the detached area. Before

• solving the problem it is convenient to introduce the following dimensionless quantities where we have defined δ through the relation δ + h = (a + h + ΔL) sinθ. From Equation 5 we obtain the following expression for the dimensionless energy release rate where we have used the geometric condition a = (a

• , the relatively higher energy release rate for a cylindrical fiber induced pull-off at significantly lower loads than mushroom-like fibers. In their analysis, the ratio of pull-off force of a mushroom-like fiber to that of a cylindrical fiber varies significantly depending on the size of the annular
