Abstract :
Two dimensional equations are derived for multiferroic circular cylindrical panels with small aspect ratio. The displacement, electrical potential and magnetic potential are assumed to be of zero-order of the radial thickness. The frequency equation is presented for a multiferroic cylindrical panel composed of CoFe2O3 and BaTiO3 with four edges simply supported. Numerical examples show clearly the effects of half-wave numbers in the axial and circumferential directions on the frequency parameters.
