In this paper, a semi-analytical finite element formulation is presented to study the magnetoelectric (ME) effect for a multilayered and multiphase magneto-electro-elastic (MEE) cylinder under various boundary conditions.Numerical studies are done to evaluate the ME coefficient for different thickness ratio of piezoelectric phase in the multilayered composite.Studies are also done for the evaluation of ME coefficient for different volume fractions of piezoelectric phase in the multiphase composite.Ansys 8.1 is used to validate the present formulation using thermal analogy concept.© 2009 Koninklijke Brill NV, Leiden.

Studies on Magnetoelectric Effect for Magneto-Electro-Elastic Cylinder using Finite Element Method

Multidiscipline Modeling in Materials and Structures

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.
