Outline of Final Research Achievements |
The friction properties of the one-dimensional atomistic models have been investigated in terms of friction transition and nonlinear atomic vibrations. The friction model depends on the interfacial interaction and initial sliding velocity. Two regimes, which are friction and superlubricity, are found. Friction regime has two sub-areas It has been found that the boundaries between Friction area and Superlubricity area look like irregular. The mechanism for the appearance of the multi peaks is complex problem; it will need to elaborately examine vibration mode signals in terms of non-linear system analysis. A scenario for the transition Superlubricity (S) mode to Friction (Fβ) could be described in terms of several non-linear vibrations such as subharmonic oscillation, summed-and-differential harmonic oscillation, superharmonic oscillation, internal resonance phenomena.
