摘      要：In this paper,by defining a general potential energy for the multiphase coupled multiferroics and applying the minimum energy principle,the coupled governing equations are *** system of equations is then discretized as a general three-dimensional(3D)finite element(FE)model based on the COMSOL *** validating the formulation,it is then applied to the analysis and design of the common sandwich structure of multiferroics *** the typical static loading,the effects of general lateral boundary conditions,material grading,nonlinearity,as well as polarization orientation on the composites are *** the magneto-electro-elastic(MEE)sandwich made of piezoelectric BaTiO_(3)and magnetostrictive CoFe_(2)O_(4)with different stacking sequences,various interesting features are observed which should be very helpful for the design of high-performance multiphase composites.
