Jamming creep of a frictional interface

Materials Science 2009-11-07 v1 Soft Condensed Matter

Abstract

We measure the displacement response of a frictional multicontact interface between identical polymer glasses to a biased shear force oscillation. We evidence the existence, for maximum forces close below the nominal static threshold, of a jamming creep regime governed by an ageing-rejuvenation competition acting within the micrometer-sized contacting asperities. Quantitative analysis of the creep curves suggests that another such mechanism might be at work within the nanometer-thick adhesive junctions.
