Multiscale Stick-Slip Dynamics of Adhesive Tape Peeling

Abstract

Using a high-speed camera, we follow the propagation of the detachment front during the peeling of an adhesive tape from a flat surface. In a given range of peeling velocity, this front displays a multiscale unstable dynamics, entangling two well-separated spatio-temporal scales, which correspond to microscopic and macroscopic dynamical stick-slip instabilities. While the periodic release of the stretch energy of the whole peeled ribbon drives the classical macro-stick-slip, we show that the micro-stick-slip, due to the regular propagation of transverse dynamic fractures discovered by Thoroddsen et al. [Phys. Rev. E 82, 046107 (2010)], is related to a high-frequency periodic release of the elastic bending energy of the adhesive ribbon concentrated in the vicinity of the peeling front.

In-situ measurement of the large strain response of the fibrillar debonding region during the steady peeling of pressure sensitive adhesives

“…Peeling experiments are performed at room temperature (23±2 o C) on a commercial PSA (3M Scotch® 600) 1 frequently studied in the literature (Barquins and Ciccotti 1997;Amouroux et al 2001;Cortet et al 2007;Cortet et al 2013;Dalbe et al 2014a;Dalbe et al 2014b;Dalbe et al 2015;Villey et al 2015). The adhesive tape is peeled from a flat bar by an Instron testing machine (model 3343), which records the peeling force F while imposing a constant pull-out velocity V ∈ [3 : 3000] µm s −1 .…”

Role of temperature in the decohesion of an elastic chain tethered to a substrate by onsite breakable links

“…It is possible to see that the main fraction in Eqs. (44) and (46) converges to 1 when Y → +∞ and y d → +∞, respectively. Thus, we can obtain the asymptotic value…”

“…(52) for increasing values of p, the final results are much more cumbersome than Eqs. (44) and (46), and therefore in this work, for simplicity, we only use Eq. (38).…”

“…Examples of the former case are the conformational transitions in polymeric and biopolymeric chains [1][2][3][4][5][6][7][8][9][10][11][12][13][14], the attachment and detachment of fibrils in cell adhesion [15][16][17][18][19][20], the unzipping of macromolecular hairpins [21][22][23][24][25][26], the sarcomeres behavior in skeletal muscles [27][28][29][30][31][32][33], and the denaturation or degradation of nucleic acids, polypeptidic chains, or other macromolecules of biological origin [34][35][36][37][38][39][40][41][42][43]. Moreover, with regard to artificial systems, we recall the peeling of a film from a substrate [44][45][46][47]…”

Spectral analysis of the stick‐slip phenomenon in “oral” tribological texture evaluation

“…The overall pattern, for example, repeated regular or irregular oscillations (Baum et al, 2014; Motchongom-Tingue, Djuidj e Kenmo e, & Kofan e, 2011) and the mean amplitude and frequency, calculated from the height and number of force peaks shown in Figure 1 (Bagga et al, 2012;Scherge & Gorb, 2013;Seo et al, 2015) can characterize stick-slip effects. Spectral analysis is useful to account for multiscale patterns composed of repeated events of different frequencies and magnitudes (Dalbe, Cortet, Ciccotti, Vanel, & Santucci, 2015;Rubinstein, Cohen, & Fineberg, 2009). The Fourier transform is traditionally used to calculate the frequency components and their corresponding magnitude distribution (Sanahuja & Briesen, 2015).…”
