THOMAS, Olivier (Centre pour la Communication Scientifique Directe (CCSD), 2021-05)
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 ...
