Journal ArticleDOI
Damping of structural vibrations with piezoelectric materials and passive electrical networks
TL;DR: In this paper, the authors investigated the possibility of dissipating mechanical energy with piezoelectric material shunted with passive electrical circuits, and derived the effective mechanical impedance for the piezolectric element shunted by an arbitrary circuit.
Journal ArticleDOI
Modelling of Piezoelectric Actuator Dynamics for Active Structural Control
TL;DR: In this article, the effects of dynamic coupling between a structure and an electrical network through the piezoelectric effect are derived. But the authors focus on the case of a cantilevered beam with surface mounted piezoceramics and indirect voltage and current drive.
Journal ArticleDOI
Piezoelectric Fiber Composites with Interdigitated Electrodes
Aaron A. Bent,Nesbitt W. Hagood +1 more
TL;DR: In this paper, two microelectromechanical models were developed that predict the composite properties and were used to examine the trends of composite properties versus fiber volume fraction for various constituent materials.
Journal ArticleDOI
Modeling of a piezoelectric rotary ultrasonic motor
TL;DR: In this article, the Rayleigh-Ritz assumed mode energy method is used to model the distributed piezoceramics and the traveling wave dynamics of the stator.
Journal ArticleDOI
Anisotropic actuation with piezoelectric fiber composites
TL;DR: In this paper, an investigation was made into the field of planar structural actuation with anisotropic active materials, and the mechanisms for creating an isotropic actuators were discussed and the impact of anisot...
