Particularly, it is demonstrated, in an accessible way,that the oscillations of the anharmonic oscillator drastically differ from thoseof a harmonic one. The main reason lies in the fact the oscillator frequency ofthe nonlinear oscillator, at large deviations, begins to depend on the amplitudeof the oscillations.roelongationamplitudefrequencyoscilatedisturbancenonlinearityamortizationbistabilityArticlehttps://doi.org/10.59295/spd2024n.108
