A new approach to nonlinear quartic oscillators

RA El-Nabulsi, W Anukool - Archive of Applied Mechanics, 2022 - Springer
In this study, we proved that damped quadratic nonlinear oscillators similar to Duffing and
Helmholtz–Duffing damped equations which emerge in bubble dynamics with time-periodic …

On the modified least action principle with dissipation

K Fitzgerald, M Massoudi, A Vaidya - European Journal of Mechanics-B …, 2021 - Elsevier
The principle of least action is a variational principle that states an object will always take the
path of least action as compared to any other conceivable path. This principle can be used …

Nonlinear oscillations of hydraulic shock absorbers

B Marinca, E Tudor - American Institute of Physics …, 2023 - ui.adsabs.harvard.edu
Most of the shock absorbers utilized for suspensions of road vehicles have asymmetric
characteristic. By neglecting the laminar character of the flow for small velocities and …
