This report is a theoretical and numerical analysis on dissipative processes in nanometers scale due to kinetic friction in a simple one-dimensional model between two atomically flat surfaces, so called Frenkel-Kontorova-Tomlinson (FKT) model. FKT model is a ductile system to study several properties for sliding surface, in particular to study the mechanism by which mechanical energy is dissipated when one body slides upon another. In condition of constant equilibrium temperature kinetic friction shows a regular intermittent behaviour between frictionless and non zero friction states in sliding process. Considering increasing temperature due to non equilibrium pumping of energy in sliding process intermittent frictionless states are destroyed. Moreover, in this paper FKT model is used in order to study the mechanisms by which mechanical energy is exchanged and dissipated when one body slides upon another. To this purpose we will show that determinant is the validity of heat Fourier law in FKT model.
