Abstract :
We investigate magnetoelectric (ME) effects in bilayer multiferroic core-shell composites in this paper. The composites
are driven by the radial magnetic field and the induced radial deformation/vibration is studied. Two
configurations are considered in a concise and uniform manner mathematically. One is spherical and the other
is cylindrical. For bilayer core-shell composites, we show that the geometric configuration has a significant effect
on the ME effect in multiferroic core-shell composites for both low-frequency and electromechanical resonance
ranges. At the low-frequency range, except for the mechanically clamped case, the ME effects in spherical multiferroic
composites are always stronger than that in cylindrical ones. At the electromechanical resonance range,
for traction-free case, the fundamental resonance frequency of the spherical multiferroic composite is higher
than that of the cylindrical one and thus the corresponding ME effect in spherical composite is stronger than
that in cylindrical one.
