Meso-Scale Dynamics of Attachment-Detachment Processes in Adhesion and Friction

Abstract

When soft and sticky materials are detached from or slid against a rigid substrate, specific types of meso-scale dynamics accompanying large deformation and pattern formation are observed. In this paper, we introduce our studies on the in-situ visualization of cavitation during debonding of soft adhesives and also of the Schallamach waves in sliding friction of adhesive gel-sheets.
