A Finite Element Model And Active Vibration Control Of Composite Beams With Distributed Piezoelectrics Using Third Order Theory
نویسندگان
چکیده
In this study, A finite element model based on the third order theory is presented for the active vibration control of composite beams with distributed piezoelectric sensors and actuators. For calculating the total charge on the sensor, the direct piezoelectric equation is used and the actuators provide a damping effect on the composite beam by coupling a negative velocity feedback control algorithm in a closed control loop. A modal superposition technique and a Newmark-β method are used in the numerical analysis to compute the dynamic response of composite beams. Algorithm for calculating the various values of variables is carried out using Matlab tool KeywordsActive vibration control, cantilever composite beam, Newmark-β method

A finite element model for extension and shear modes of piezo-laminated beams based on von Karman's nonlinear displacement-strain relation
Piezoelectric actuators and sensors have been broadly used for design of smart structures over the last two decades. Different theoretical assumptions have been considered in order to model these structures by the researchers.

Vibration of laminated composite and sandwich plate under thermal loading is studied in this paper. A refined higher order theory has been used for the purpose. In order to avoid stress oscillations observed in the implementation of a displacement based finite element, the stress field derived from temperature (initial strains) have been made consistent with total strain field. So far no study ...
