A finite element method is used to analyse the free vibrations of MEE truncated conical shell. Three Boundary Conditions – Clamped-Free (C-F), Simply-Supported (S-S), Clamped-Clamped (C-C) are considered to study the behaviour of magneto-electro-elastic truncated conical shell with constant thickness. The study is made to identify the effect of magnetic and electric coupling on the frequencies of conical shell. Frequency characteristics on conical shells are discussed by varying the semi vertex angles 20°, 35° and 50°. The magneto-electro-elastic truncated conical shells behaviour indicates that as frequency increases with increase in circumferential mode.
