Free vibration studies of multiphase and layered magneto-electro-elastic beam for BaTiO3-CoFe2O4 composite is carried out. In-plane plate finite-element analysis is used to obtain the behaviour of magneto-electro-elastic beam. Studies are carried out for beams for different boundary conditions, as may be applicable in design of smart sensors/actuators. The ANSYS package is used to validate the results obtained by the computer code developed for piezoelectric (PE) beam. Plane stress condition is used for the Euler-Bernouli magneto-electro-elastic beam. © 2006 Elsevier Ltd. All rights reserved.
