Description
Summary:A micromechanical model based on the bridging theory is proposed for predicting the effective coefficients of two-phase magnetoelectric composites. The 17 different coefficients, including the effective elastic, piezoelectric, piezomagnetic, dielectric, magnetic permeability and magnetoelectric coupling coefficients, are divided into two groups based on the analysis of existing results of the classical micromechanical models. The relationship between the strain field, electric field and the magnetic field of two constituents is presented. The results are well matched with the finite element results. The classical models for predicting the effective coefficients of magnetoelectric composites can be covered flexibly by the presented unified micromechanical model.
