Simulation of Instabilities in the Adhesive Contact of Rough Elastic Bodies
Very sticky rough surfaces separate in an intermittent fashion: parts of the contacting area break off. These instabilities lead to adhesion hysteresis and friction and may play a role in contact charging. My simulations of contact mechanics complement the experimental investigations of Qiwei Hu and Ravi Divakar to correlate mechanics and charge transfer at the microscale.
