中文摘要：

在这研究，我们调查非线性的联合磁电(我) 巨大的 magnetostrictive/piezoelectric 的效果合成柱体。ME 材料的非线性的组成的关系被考虑，并且 ME 效果上的非线性的材料性质的影响分别地为静态、动态的案例被调查。ME 效果上的不同限制条件的影响被讨论。在就非线性的材料性质而言的动态案例中，双频率我反应(反应频率是两次应用磁性的频率)被获得并且讨论，它能被用来解释有频率 f 的输入信号在我与 2 f 在被变换成输出信号的实验现象把压成薄片的结构。一些计算在上非线性我效果被进行。获得的结果显示非线性的材料性质影响大小不仅我在在动态案例中的静态的案例而且 ME 反应频率中的效果。

英文摘要：

In this study, we investigate the nonlinear cou- pling magneto-electric （ME） effect of a giant magnetostric- tive/piezoelectric composite cylinder. The nonlinear consti- tutive relations of the ME material are taken into account, and the influences of the nonlinear material properties on the ME effect are investigated for the static and dynamic cases, respectively. The influences of different constraint conditions on the ME effect are discussed. In the dynamic case considering nonlinear material properties, the double frequency ME response （The response frequency is twice the applied magnetic frequency） is obtained and discussed, which can be used to explain the experiment phenomenon in which the input signal with frequency f is converted to the output signal with 2f in ME laminated structures. Some calculations on nonlinear ME effect are conducted. The obtained results indicate that the nonlinear material properties affect not only the magnitude of the ME effect in the static case but also the ME response frequency in the dynamic case
