Abstract
In this article, the controlled frequency response of three-phase smart magneto-electro-elastic (TPS-MEE) composite plates treated with active constrained layer damping (ACLD) is studied using finite element (FE) method. The composite consists of Cobalt Ferrite piezomagnetic matrix embedded with carbon fibers in the piezoelectric shell. A three-dimensional FEformulation is developed through the principle of virtual work. The ACLD treatment comprises of the constraining layer of 1-3 piezoelectric composite as well as the constrained layer of viscoelastic material. The coupling characteristics and hence the stiffness of the smart composite significantly change with the thickness of the piezoelectric interphase. Therefore, emphasis is made on the effect of ACLD treatment on the vibration attenuation of the TPS-MEE plates with different interphase thickness and material. In addition, special attention is paid to the influence of geometrical skewness associated with different interphase thickness on the vibration amplitude and the control voltage. © 2020 IOP Publishing Ltd.
