Available in PDF, EPUB and Kindle. Book excerpt: Conventionally, the energy required to fracture an interface is predicted to be directly proportional to the thermodynamic work of adhesion. It has been observed, however, that on some low energy surfaces, the fracture energy of an adhesive deviates significantly from this rule. In viscoelastic systems, it is well known that most of the energy is dissipated by the viscous bulk materials near the crack tip region. What is, perhaps, not so widely known is that for a crack propagating at an asymmetric interface, a substantial amount of energy can be dissipated through a frictional mechanism near the crack tip region. This energy dissipation due to friction at and near the crack tip is being proposed to account for the discrepancies observed with adhesion on low energy surfaces. The objective of this research is to investigate the contribution of interfacial friction and associated slip processes to the total fracture energy.
