Summary

This paper describes a simple model of adhesive failure used to describe the physical processes that result in bimodal nature of tack curves in experiments. They consider two parallel plates attached to each other by an array of <math> N(t)</math> nonlinear springs, which dissociate as the plates are pulled apart at a constant velocity. They describe the dissociation rate by the equation:

<math> k(t)=k_{0}\exp\left(\frac{\gamma vt}{bL(1-vt/L)}\right)</math>
