Dynamics of weakly overdamped nonlinear oscillators

The dynamics of weakly overdamped nonlinear oscillators is studied. Weak overdamping is defined as a slight excess in the value of the damping decrement corresponding to the eigenfrequency of an oscillator. Based on exact solutions to the problem, it is shown that in approaching equilibrium, relaxat...

Zusammenfassung:	The dynamics of weakly overdamped nonlinear oscillators is studied. Weak overdamping is defined as a slight excess in the value of the damping decrement corresponding to the eigenfrequency of an oscillator. Based on exact solutions to the problem, it is shown that in approaching equilibrium, relaxation dynamics is replaced by a quasi-oscillation process, provided that the initial shift exceeds the threshold value.
