This study presents a comprehensive investigation on functionally graded (FG) graphene reinforced aluminium cantilever rectangular plates under aerodynamic loads. Two-way loosely coupled fluid structure interaction (FSI) is implemented by coupling finite element analysis (FEA) and computational fluid dynamics (CFD). FEA models are developed using FG graphene nanoplatelets (GPL) reinforced aluminium composite structures with different GPL distribution patterns. Fluid domain is modelled using finite volume method and FSI module is then used to connect FEA with the CFD code. The simulation results of FSI indicate that the maximum stress of the plate can be efficiently reduced with satisfactory aerodynamic performance after aeroelastic tailoring, depending on specific GPL distribution patterns. It is shown that in conjunction with aeroelastic tailoring technique, the composite plate can achieve optimized structural and aerodynamic performance. The present results of the FG graphene reinforced aluminium plates offer useful design guideline for their applications as the structural components in aeronautical fields.

本研究对气动载荷下的功能梯度 (FG) 石墨烯增强铝悬臂矩形板进行了全面研究。双向松散耦合流固耦合（FSI）是通过耦合有限元分析（FEA）和计算流体动力学（CFD）来实现的。FEA 模型是使用具有不同 GPL 分布模式的 FG 石墨烯纳米片 (GPL) 增强铝复合结构开发的。使用有限体积法对流体域进行建模，然后使用 FSI 模块将 FEA 与 CFD 代码连接起来。FSI 的仿真结果表明，根据特定的 GPL 分布模式，经过气动弹性剪裁后，板的最大应力可以有效降低，空气动力学性能令人满意。结果表明，结合气动弹性剪裁技术，复合板可以实现优化的结构和空气动力学性能。目前 FG 石墨烯增强铝板的结果为其作为航空领域结构部件的应用提供了有用的设计指南。
