Abstract

The numerical analysis carried out in the present paper is one of the first analyses focused on the application of porous ferroelectric materials in context of active vibration attenuation. The active vibration damping of smart plate panel is achieved with ferroelectric ceramics. The plate panel is modelled as composite structure. The finite element method is implemented to model the piezo-laminated plate panel and to demonstrate the static as well as dynamic analysis of structural vibrations subjected to external loading. Modeling of piezo-laminated structure is based on the assumptions of first-order shear deformation theory (FSDT). Ferroelectric ceramic layers are modelled using linear piezoelectric theory. The performance of porous ferroelectric ceramics is compared with dense ferroelectric ceramics in context of active vibration control. The numerical study reveals that the vibration amplitude of the structural vibration can be attenuated by approximately 83% and 91% after 1 second corresponding to the application of dense piezoelectric material and 30% porous piezoelectric material respectively.
