Vibration of piezolaminated cylinders

Abstract

The Axisymmetric and Flexural vibration of an infinite newlinepiezocomposite solid and hollow cylinder made of inner solidhollow and newlineouter hollow piezoelectric layer of 6 mm class bonded together by an newlineisotropic Carbon FiberReinforced Plastics CFRP layer is studied Also the newlineFlexural vibration of an infinite piezolaminated five layered solid cylinder newlinemade of piezoelectric layers of 6 mm class and isotropic CFRP layers is newlinestudied The frequency equations are obtained for the traction free surfaces newlinewith continuity conditions at the interfaces Numerical results corresponding newlineto the axial and flexural vibrations of the piezocomposite cylinder newlinePZT4CFRPPZT4 and PZT4CFRPPZT4CFRPPZT4 are carried out and newlinethe dispersion curves are compared with a similar model embedding a Linear newlineElastic Material with Voids LEMV as middle layer newline newline
