Linear Buckling and Vibration Behavior of Piezoelectric/Piezomagnetic Beam under Uniform Magnetic Field

Abstract:

The constitutive equations of MEE materials are used to derive the finite element equations involving the coupling between mechanical, electrical and magnetic fields. The candidate materials for this study are piezoelectric (BaTiO₃) and magnetostrictive (CoFe₂O₄) material. The linear buckling and vibration behavior of layered MEE beam under uniform magnetic field is carried out using finite element method. The present study is limited to clamped-clamped boundary conditions. The influence of stacking sequences and piezoelectric coupling on critical buckling magnetic field and vibration behaviour is investigated.
