“…The phenomenon remains highly non-linear and the dynamics shows a variety of instabilities and structures [2]. Several dynamical models were developed with an increasing degree of realism, leading to an increasing complex dynamics [3,4,5,6,7]. Each model is characterized by a series of seemingly trivial assumptions which progressively revealed to have a crucial effect on the dynamical aspects of the problem.…”

Using a high speed camera, we study the peeling dynamics of an adhesive tape under a constant load with a special focus on the so-called stick-slip regime of the peeling. It is the first time that the very fast motion of the peeling point is imaged. The speed of the camera, up to 16000 fps, allows us to observe and quantify the details of the peeling point motion during the stick and slip phases : stick and slip velocities, durations and amplitudes. First, in contrast with previous observations, the stick-slip regime appears to be only transient in the force controlled peeling. Additionally, we discover that the stick and slip phases have similar durations and that at high mean peeling velocity, the slip phase actually lasts longer than the stick phase. Depending on the mean peeling velocity, we also observe that the velocity change between stick and slip phase ranges from a rather sudden to a smooth transition. These new observations can help to discriminate between the various assumptions used in theoretical models for describing the complex peeling of an adhesive tape. The present imaging technique opens the door for an extensive study of the velocity controlled stick-slip peeling of an adhesive tape that will allow to understand the statistical complexity of the stick-slip in a stationary case.

“…Indeed, the strain energy release rate exhibits two stable branches separated by an unstable branch. Detailed studies by Maugis and Barquins [1] and others [3,4,5] show that the nature of the wave forms of the pull force exhibits sinusoidal, sawtooth and highly irregular wave patterns. Gandur et al [6] have carried out a dynamical analysis of the force waveforms and of acoustic emission signals, and report chaotic dynamics at the upper end of the pull velocities [6].…”

“…They report that the system of equations displayed periodic and chaotic stick-slip solutions. However, it was later recognized that the stick-slip oscillations were not obtained as a natural consequence of the equations of motion [4,11,12] as the jumps in the rupture speed were introduced externally once the velocity exceeded the limit of stability. Later, Ciccotti et al [4] interpret stick-slip jumps as catastrophes with the belief that the jumps in the rupture velocity cannot be obtained from these equations of motion [4].…”

Missing physics in stick-slip dynamics of a model for peeling of an adhesive tape

It is now known that the equations of motion for the contact point during peeling of an adhesive tape mounted on a roll introduced earlier are singular and do not support dynamical jumps across the two stable branches of the peel force function. By including the kinetic energy of the tape in the Lagrangian, we derive equations of motion that support stick-slip jumps as a natural consequence of the inherent dynamics. In the low mass limit, these equations reproduce solutions obtained using a differential-algebraic algorithm introduced for the earlier equations. Our analysis also shows that mass of the ribbon has a strong influence on the nature of the dynamics.

PSA performances and viscoelastic properties of SIS‐based PSA blends with H‐DCPD tackifiers

Hotmelt pressure sensitive adhesives (PSAs) usually contain styrenic block copolymers like styrene-isoprene-styrene (SIS), SBS, SEBS, tackifier, oil, and additives. These block copolymers individually reveal no tack. Therefore, a tackifier is a low molecular weight material with high glass transition temperature (T g ), and imparts the tacky property to PSA. The SIS block copolymer with different diblocks was blended with hydrogenated dicyclopentadiene (H-DCPD tackifier), which has three kinds of T g . PSA performance was evaluated by probe tack, peel strength, and shear adhesion failure temperature. PSA is a viscoelastic material, so that its performance is significantly related to the viscoelastic properties of PSAs. We tested the viscoelastic properties by dynamic mechanical analysis and the thermal properties by differential scanning calorimeter to investigate the relation between viscoelastic properties and PSA performance.
