| 中文摘要: |
| 采用平均场Mori-Tanaka模型,计算了三相复合材料的有效磁电弹性模量,研究了复合材料磁电系数与微观结构之间关系;结果表明掺杂相的体积分数与颗粒形状系数对复合材料的有效磁电系数有很大的影响,这些结果可为复合材料的实验设计提供理论参考和指导。 |
| 英文摘要: |
| 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. |
