Simple model on debonding of soft adhesives

Author affiliations

Abstract

We propose a simple theoretical model describing the debonding process of soft adhesives in the probe-tack test. In this model, the expansion dynamics of interfacial cavities is determined by the balance between the strain energy release rate and the rate-dependent fracture energy. As a result, we obtain analytical solutions for the cavity size, stress–strain curve, peak stress, strain at the peak stress, maximum strain, as well as the adhesion energy. Furthermore, we discuss the validity of our theoretical results by comparing them with experiments.
