Abstract

In this article, the dynamic response of the curved Fiber-Metal-Laminate sandwich beam with flexible core, under low-velocity impact on the top of the face sheet, is investigated. Higher order shear deformation theory is used and strain-displacement, stress-strain equations, and compatibility conditions between the core and face sheets are applied to obtain the displacement field of the core. The results of model are compared with the results of ABAQUS simulation and the latest researches. The effects of beam curvature angle, core thickness, and its modulus of elasticity, mass and velocity of impactor on radial displacements and contact force histories are reviewed.

摘要

在本文中，研究了弯曲的具有柔性芯的纤维金属层压夹层梁在面板顶部的低速冲击下的动态响应。采用高阶剪切变形理论，应用应变-位移、应力-应变方程以及芯板与面板之间的相容条件来获得芯板的位移场。将模型结果与ABAQUS仿真结果和最新研究结果进行了比较。回顾了梁曲率角、核心厚度及其弹性模量、冲击器质量和速度对径向位移和接触力历史的影响。
