Title: Time-decaying magnetoelectric effects in multiferroic fibrous composites with a viscous interface

Abstract

This paper addresses the time-dependent magnetoelectroelastic responses of multiferroic fibrous composites with a viscous interface. First, the problem of an isolated multiferroic fiber embedded in an infinite multiferroic matrix is rigorously solved. It is observed that the internal magnetoelectroelastic field such as stresses, electric displacements, and magnetic inductions inside an isolated multiferroic fiber is uniform but time dependent. The Mori-Tanaka mean-field method is then utilized to derive an extremely concise expression of the time-dependent effective moduli of the multiferroic fibrous composite. The numerical results demonstrate that the viscosity of the interface will cause a time-decaying magnetoelectric effect of the BaTiO{sub 3}-CoFe{sub 2}O{sub 4} fibrous composite. As the time approaches infinity the magnetoelectric effect will approach zero due to the fact that a viscous interface will finally evolve into a free-sliding one which does not sustain shear stress. This interesting feature should be particularly important to the analysis and design of multiferroic composites where the interface is utilized to enhance the magnetoelectric effect.
