THOMAS, Olivier; GIRAUD-AUDINE, Christophe (Elsevier BV, 2022-05)
In this paper, a semi-passive nonlinear piezoelectric shunt absorber is presented, aiming at attenuating the vibration of a resonant elastic structure under external excitation. This is done by connecting the elastic ... -

We compare different models describing the buckling, post-buckling and vibrations of elastic beams in the plane. Focus is put on the first buckled equilibrium solution and the first two vibration modes around it. In the ...

A nonlinear piezoelectric shunt absorber with 2:1 internal resonance: experimental proof of concept Article dans une revue avec comité de lecture;THOMAS, Olivier; GIRAUD-AUDINE, Christophe (IOP Publishing, 2022-01)
An experimental proof of concept of a new semi-passive nonlinear piezoelectric shunt absorber, introduced theoretically in a companion article, is presented in this work. This absorber is obtained by connecting, through a ...

Article dans une revue avec comité de lecture;SHEN, Yichang; TOUZÉ, Cyril; THOMAS, Olivier; GIRAUD-AUDINE, Christophe (Springer Science and Business Media LLC, 2022-08)
This article considers the nonlinear dynamics of coupled oscillators featuring strong coupling in 1:2 internal resonance. In forced oscillations, this particular interaction is the source of energy exchange, leading to a ...
