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 ... -
