We investigate the effectiveness of a vibration absorber on the vortex-induced vibration response of turbine blades during the frequency lock-in phase. A reduced order model is considered for a turbine blade and a von der Pol oscillator is used to mo

In this paper, we investigate the nonlinear vibration of a metamaterial structure that consists of a rotating cantilever beam attached to a periodic array of spring–mass–damper subsystems deployed for vibration suppression. The full nonlinear mod

We investigate the potential of a novel hybrid excitation of the tail for a robotic fish. The tail consists of an ionic polymer-metal composite (IPMC) beam excited at its base. A model of the beam dynamics under base excitation, IPMC actuation mechan

In this paper, we investigate the nonlinear vibrations of a metamaterial structure that consists of a host Euler–Bernoulli beam attached to a periodic array of spring-mass-damper subsystems deployed for vibration absorption. The main objective is t

Significant progress has been made in the last few decades in developing the technology of large-scale wind turbines to generate power from the wind flow. However, only few numerical and experimental studies have been carried out to investigate the p
