This paper investigates the static and dynamic performances of sandwich plates with magnetorheological elastomer (MRE) core, in which the MRE core includes two copper wire layers, two inner metal layers, and one MRE layer. First, based on the complex modulus method, the Jolly theory and the pre-defined magnetic coefficients, the dynamic moduli, and loss factors of MRE are assumed as a function of magnetic induction intensity. Furthermore, a theoretical model of the MRE sandwich plates (MRESPs) is proposed, which considers the internal magnetic field excitation and four types of panel materials, namely fiber-reinforced polymer (FRP), fiber-reinforced polymer with carbon nanotubes (CNT-FRP), metal and fiber-metal hybrid (FMH) panels. After the deformation and energy equations are derived to solve the static bearing stiffness, dynamic stiffness, and damping parameters, some literature results are employed to provide the initial validation of the model developed. Subsequently, four MRESP specimens with the FRP, CNT-FRP, metal, and FMH panels are fabricated and measured to further verify the model as well as to evaluate the mechanical performance. The influence of critical geometric and material parameters related to MRE on static and dynamic properties is also discussed to summarize some practical conclusions for engineering applications.

本文研究了具有磁流变弹性体 (MRE) 芯的夹层板的静态和动态性能，其中 MRE 芯包括两个铜线层、两个内部金属层和一个 MRE 层。首先，基于复模量法、Jolly 理论和预定义的磁系数、MRE 的动态模量和损耗因子被假设为磁感应强度的函数。此外，提出了MRE夹层板（MRESPs）的理论模型，该模型考虑了内部磁场激发和四种面板材料，即纤维增强聚合物（FRP）、碳纳米管纤维增强聚合物（CNT-FRP） )、金属和纤维金属混合 (FMH) 面板。导出变形和能量方程后求解轴承的静刚度、动刚度、和阻尼参数，一些文献结果被用来提供模型开发的初步验证。随后，制作并测量了四个具有 FRP、CNT-FRP、金属和 FMH 面板的 MRESP 试样，以进一步验证模型并评估机械性能。还讨论了与 MRE 相关的关键几何和材料参数对静态和动态特性的影响，以总结一些工程应用的实际结论。
