Free Vibration Analysis of Multiphase Magneto-Electro-Elastic Composite Conical Shells

Abstract

Objectives: In the present article, free vibration of multiphase Magneto-Electro-Elastic (MEE) conical shell having a uniform thickness is examined for Clamped-Free (C-F) boundary condition. Method: The study is carried out using a semi-analytical approach for different volume fractions (Vf ) 0, 0.2, 0.6 and 1.0 of BaTiO3 in BaTiO3-CoFe2O4 smart composite conical shell for three different semi-vertex angles 20o,35o and 50o. The piezoelectric (Pe) and piezomagnetic (Pm) phase on natural frequencies of MEE truncated conical shells are discussed for different circumferential modes. Findings: The parametric study indicates that natural frequency decrease with an increase in Vf of BaTiO3 in magnetoelectro-elastic truncated conical shells. Novelty: Studies on MEE constant thickness truncated conical shell using BaTiO3 and CoFe2O4 as (Pe) & (Pm) smart composite for clamped-free boundary condition to analyse the effect of the frequency with different semi-vertex angle and cone heights. Present commercial FEA software tools are limited to 2 coupling fields. In this research, coupling between 3 fields considered for MEE material. Hence, a computer code is developed to study the influence coupling between electric, elastic and magnetic fields, which can be used for any combinations of boundary conditions and volume fractions.
