Abstract
We report an extensive experimental study of a detachment front dynamics instability, appearing at microscopic scales during the peeling of adhesive tapes. The amplitude of this instability scales with its period as , with a prefactor evolving slightly with the peel angle , and increasing systematically with the bending modulus of the tape backing. Establishing a local energy budget of the detachment process during one period of this microinstability, our theoretical model shows that the elastic bending energy stored in the portion of tape to be peeled is converted into kinetic energy, providing a quantitative description of the experimental scaling law.

Microscopic Theory for Peeling Tape
Published 15 February 2019
Extensive experiments lead to a theory that describes the microscale, jerky process involved in the seemingly smooth peeling of tape from a surface.
