中文摘要：

针对两种不同形式（压电-铁磁-压电,铁磁-压电-铁磁）的磁电层状复合材料,研究了热场环境下磁电层状复合材料的力、热、电以及磁的多场耦合特征,给出了磁电层状复合结构的位移、应力、电势以及磁势的变化规律,探讨了界面过渡层厚度变化及其不同界面过渡方式对磁电复合材料的位移、应力、电势和磁势的影响。研究结果表明,界面过渡层对应力特征、电势和磁势的分布具有非常重要的影响,尤其对磁势的分布特征影响尤为明显,这些结果可为磁电层合材料的结构设计和可靠性分析提供参考和依据。

英文摘要：

The electro-magneto-thermo-elastic coupling characteristics of a laminated magneto-electric plate with consideration of the interfacial layer were investigated.The distribution characteristics of the displacements,the stresses,the electric potentials and the magnetic potentials of the laminated magneto-electric plate were discussed and displayed.The influence of the interfacial layer thickness and different transition approaches of the material properties of the interfacial layer on the displacements,the stresses,the electric potentials and the magnetic potential of the plate were also studied.The numerical result shows that the interfacial transition layer has very important effect on the distribution of stress,electric potential and magnetic potential,especially for the distribution of magnetic potential,these results may be very useful in the functional design and the reliability analysis of magnetoelectricity laminated structures.
