AN ANALYSIS OF A PIEZO-ELASTIC RESTRICTOR USING A CAPACITIVE SHUNT

The study investigates the control of structural response using collocated piezoelectric elements mounted on both sides of beam. A capacitive shunt is introduced into the circuitry to provide passive control of the beam’s configuration. The energy method is used to develop the structure’s governing...
