In this paper transient response of multiphase magneto-electro-elastic cantilever beam is presented using finite element method. Numerical studies are presented for different volume fraction of the piezoelectric phase (BaTio 3) in magneto-electro-elastic (CoFe2 O4- BaTiO3) composite under clamped-free boundary condition. Newmark Beta method is employed to find the transient response of the beam. A comparison between the elastic, coupled, and uncoupled response of 0.6 volume fraction magneto-electro-elastic beam is also presented. Ansys 8.1 has been used to validate the displacement (uZ) and electric potential (φ) for (PZT)-epoxy mixed component (PECP) material with computer code.

Transient Dynamic Response of Cantilever Magneto-Electro-Elastic Beam Using Finite Elements

International Journal of Computational Methods in Engineering Science and Mechanics

The transient response of a simply supported layered cylinder made of a three-phase magneto-elecrolastic (MEE) composite, consisting of an elastic matrix reinforced with piezoelectric and piezomagnetic fiber has been studied by developing a semianalytical finite element method employing fourth-order Runge-Kutta method. Numerical results are presented for different volume fractions of piezomagnetic fiber in a three-phase MEE material with simply supported boundary conditions. A study of the transient responses of (PZT)-epoxy mixed component (PECP), (Terfenol-D)-epoxy mixed components (MSCP), barium titanate (BaTiO3) and a two phase magneto-electro-elastic layered cylinder, under simply supported boundary conditions has also been presented. A comparison between the elastic and the coupled responses of the MEE cylinder is presented as well. Ansys 8.1 is used to validate the present code for the response of cylinder made of PECP and MSCP materials.

Transient response of magneto-electro-elastic simply supported cylinder using finite element

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.
