•The length of the piezoelectric/piezomagnetic composite cylinder has significant effect on the magnetoelectric (ME) effect.•The longer the length is, the larger the maximum static ME effect is.•A cylinder with a longer length has lower resonance frequencies.•The increase of the length enhances the first few resonance peaks.
This work presents a three-dimensional exact solution to axisymmetric vibrations of a simply-supported piezoelectric/piezomagnetic composite cylinder. Both the static and harmonic driving magnetoelectric (ME) effects of the composite structure are investigated. It is shown in the numerical results that the length of the composite cylinder has significant effect on the ME effect and cannot be simply neglected. The increase of the length of the cylinder can enhance the static ME effect, while in the frequency driving case the increase of the length can decrease the resonance frequencies and enlarge the first few resonance peaks. The distributions of the electric potential in the piezoelectric layer are plotted to present the magnitude of the electric potential for each length.
