the stick–slip mode of boundaryfriction. An analytical description and numerical simulation with radial distributions of the order parameter, stress and strain were performed to investigate the spatial inhomogeneity. It is shown that in the case when the driving device is connected to the upper part
of the friction block through an elastic spring, the frequency of the melting/solidification phase transitions increases with time.

The boundaryfriction
between the asperities. A specific case of boundaryfriction is friction between two atomically flat surfaces separated by a layer of lubricant with thickness of a few atomic diameters [1][2], or even monolayers [3]. Such type of friction mode plays an important role in applied mechanics as it often

interference reflection microscopy results indicate that boundaryfriction might be responsible for the friction [49][68]. However, although first results indicate that the mediating fluid layer in insect pads might be thinner than previous estimates [69], so far there is no experimental evidence for the
