Sliding Friction in the Frenkel-Kontorova Model
Abstract
A two-dimensional Frenkel-Kontorova model under a steady external force is used to study the nonlinear sliding friction between flat macroscopic surfaces with a lubricant layer in between. The nonequilibrium properties of the model are simulated by a Brownian molecular dynamics and results are obtained as a function of temperature and a microscopic friction parameter η.
