The deflection behavior of the fiber-metal laminated structures is envisaged in this research using higher-order deformation kinematics and large (finite) deformations of geometries via Green–Lagrange strain. The panel governing equation is derived using variational principle and solved numerically considering the nonlinear finite element (FE) steps. The necessary responses are obtained using in-house MATLAB computer code and compared with an in-house simulation model (prepared in ANSYS) and experimental data (using in-house experimental set-up). The results are verified and agree with the published data available in the open domain. The proposed model results show better consequences compared to the simulation results. The detailed responses are computed for the variable geometrical conditions (i.e. aspect ratio, end support, side-to-thickness ratio), loading and stacking sequences, including the metal layer placing. The inferences indicate the importance of nonlinearity in the framework of a higher-order kinematic model for analysing the metal laminated structure.

本研究使用高阶变形运动学和通过格林-拉格朗日应变产生的大（有限）几何变形来设想纤维金属层压结构的偏转行为。利用变分原理导出面板控制方程，并考虑非线性有限元 (FE) 步骤进行数值求解。使用内部 MATLAB 计算机代码获得必要的响应，并与内部仿真模型（在 ANSYS 中准备）和实验数据（使用内部实验装置）进行比较。结果经过验证并与开放域中可用的已发布数据一致。与模拟结果相比，所提出的模型结果显示出更好的结果。针对可变几何条件（即纵横比、端部支撑、边厚比）、加载和堆叠顺序（包括金属层放置）计算详细响应。这些推论表明了非线性在用于分析金属层压结构的高阶运动模型框架中的重要性。
