摘要：

We present an experimental investigation of the non-stationary frictional properties of multicontact interfaces between rough elastomers and rough hard glass at low velocities (not more than 200 mum s(-1)). These systems, for which the deformation contribution to friction is negligible, are shown to exhibit a phenomenology that is similar to what is observed for non-elastomeric materials in the same multi-contact configuration, and which are quantitatively described by the state- and rate-dependent friction laws. This permits us to identify clearly the two contributions to adhesive friction which are mixed in steady sliding: the interfacial shear stress, which appears as thermally activated formation and breaking of molecular bonds, and the real area of contact which evolves through viscoelastic creep of the load bearing asperities.
