Stick-Slip Dynamics in Peeling of an Adhesive Tape

The book focuses on stick-slip dynamics in peeling of an adhesive tape. The objective is to carry out comprehensive investigations of a spatio-temporal model for peeling of an adhesive tape to understand the origin of intermittent peeling of an adhesive tape and its connection to acoustic emission(AE). The nature of the peel front exhibits rich spatio-temporal patterns ranging from smooth, rugged and stuck-peeled configurations. Interestingly, the studies show one-to-one correspondence between a sequence of peel front configurations and the model acoustic energy. The model provides insight into several statistical and dynamical features of the experimental AE signals including the transition from burst type acoustic emission to continuous type with increasing pull velocity and the connection between acoustic emission and stick-slip dynamics. The model predicts chaotic AE signals. To verify this prediction we have carried out the time series analysis of acoustic emission data obtained over a wide range of pull velocities that show the chaotic dynamics
