Buckling and vibration analysis of multiphase magnetoelectroelastic beam

In this paper, linear buckling and vibration behaviour of multiphase magnetoelectroelastic (MEE) cantilever beam is analysed using finite element approach. The constitutive equations for the magnetoelectroelastic materials are used to derive finite element equations involving the mechanical, electrical and magnetic fields for the structure. The multiphase magnetoelectroelastic beam consists of piezomagnetic (CoFe2O4) matrix reinforced by piezoelectric (BaTiO3) material for different volume fraction. The influences of material constants on critical buckling load were studied. Numerical study on multiphase magnetoelectroelastic beam with different volume fraction was attempted.
