JFET_V3_N1_RP5 Nelson V.K. Nehru E.S. Journal on Future Engineering and Technology 2230 – 7184 3 1 60 64 Axisymmetric Vibration, Solid Cylinders, composite, CFRP, Piezoelectric Axisymmetric vibration of an infinite piezocomposite solid cylinder made of inner solid and outer hollow piezoelectric layer of 6mm-class bonded together by an isotropic CFRP (Carbon fiber-reinforced plastics) layer is studied. The frequency equations are obtained for the traction free surfaces with continuity condition at the interfaces. Numerical results are carried out for the cylinder PZT4/CFRP/PZT4 and the dispersion curves are compared with that of a solid piezoelectric cylinder and a similar model embedding a linear elastic material with voids (LEMV).
