摘要
本研究探讨了具有超材料蜂窝芯层和双功能分级(FG)超刚性表层的夹层复合纳米板的三维热机械波传播行为。由于其在高温应用中的潜力,蜂窝芯层首选纯镍(Ni),表层首选 Al2O3/Ni 陶瓷金属基体。石墨烯小板块(GPL)在金属陶瓷基体中以 U 型、X 型和 O 型三种不同模式进行功能分布,其幂律分布为表层提供了双重石墨烯特性。芯层和表层以及增强 GPL 的机械和热材料特性与温度有关。温度在板厚度上的变化规律被认为是非线性的。通过将正弦高阶剪切变形理论(SHSDT)与非局部积分弹性和应变梯度弹性理论相结合,可获得夹层纳米板的运动方程。利用汉密尔顿原理建立了波方程。通过参数模拟和图形表示,分析了蜂窝尺寸变量、波数、幂律指数、GPL 分布模式、GPL 重量比和温升对超刚性夹层板中三维波传播的影响。分析结果表明,夹层纳米板的三维波传播可根据所需的参数和条件进行显著改变或调整。因此,所提出的夹层结构有望为高温或低温环境下的航空、航天和潜艇飞行器中的雷达/声纳隐形应用、保护微机电设备免受高噪音和振动的影响、软机器人应用以及可穿戴健康和防护设备应用做出重要贡献。
3D wave dispersion analysis of graphene platelet-reinforced ultra-stiff double functionally graded nanocomposite sandwich plates with metamaterial honeycomb core layer
This research addresses the three-dimensional thermomechanical wave propagation behavior in sandwich composite nanoplates with a metamaterial honeycomb core layer and double functionally graded (FG) ultra-stiff surface layers. Due to its potential for high-temperature applications, pure nickel (Ni) is preferred for the honeycomb core layer, and an Al2O3/Ni ceramic-metal matrix is preferred for the surface layers. The functional distribution of graphene platelets (GPLs) in three different patterns, Type-U, Type-X, and Type-O, in the metal-ceramic matrix with a power law distribution provides double-FG properties to the surface layers. The mechanical and thermal material characteristics of the core and surface layers, as well as the reinforcing GPLs, are temperature-dependent. The pattern of temperature variation over the plate thickness is considered to be nonlinear. The sandwich nanoplate’s motion equations are obtained by combining the sinusoidal higher-order shear deformation theory (SHSDT) with nonlocal integral elasticity and strain gradient elasticity theories. The wave equations are established by using Hamilton’s principle. Parametric simulations and graphical representations are performed to analyze the effects of honeycomb size variables, wave number, the power law index, the GPL distribution pattern, the GPL weight ratio, and the temperature rise on three-dimensional wave propagation in an ultra-stiff sandwich plate. The results of the analysis reveal that the 3D wave propagation of the sandwich nanoplate can be significantly modified or tuned depending on the desired parameters and conditions. Thus, the proposed sandwich structure is expected to provide essential contributions to radar/sonar stealth applications in air, space, and submarine vehicles in high or low-temperature environments, protection of microelectromechanical devices from high noise and vibration, soft robotics applications, and wearable health and protective equipment applications.
期刊介绍:
Mechanics of Time-Dependent Materials accepts contributions dealing with the time-dependent mechanical properties of solid polymers, metals, ceramics, concrete, wood, or their composites. It is recognized that certain materials can be in the melt state as function of temperature and/or pressure. Contributions concerned with fundamental issues relating to processing and melt-to-solid transition behaviour are welcome, as are contributions addressing time-dependent failure and fracture phenomena. Manuscripts addressing environmental issues will be considered if they relate to time-dependent mechanical properties.
The journal promotes the transfer of knowledge between various disciplines that deal with the properties of time-dependent solid materials but approach these from different angles. Among these disciplines are: Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Rheology, Materials Science, Polymer Physics, Design, and others.
