Periodic Solutions of Some Differential Equations that Show the Non-Linear Vibrations of the Mechanical Systems
(Universitatea "Dunarea de Jos" din Galați, 2009)
Many phenomenons of mechanical nature possess non-linear
vibrations, their mathematical forming operation leading to differential
equations or to systems of differential non-linear equations.
In this work it is shown ...
About the Vibrations of the Mechanical Systems with Non-Linear Damping
(Universitatea "Dunarea de Jos" din Galați, 2009)
This work will analyze the non-linear vibrations of the mechanical
systems, actually the ones with non-linear damping. If we consider
