Free vibration of multiferroic simply supported circular cylindrical panels

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.
