| Abstract: | A mean field Mori-Tanaka model was developed to calculate the effective magneto-electro-elastic moduli of matrix-based three-phase multi-ferroic composites, and the variations of magnetoelectric coefficients of the composites with respect to the micro-structural features have been investigated. The results show a strong influence of volume fraction and shape aspect ratios of constituent phases on the effective magneto-electric coefficients. These numerical results provide guidelines for the experimental design of the multi-ferroic composite. |
