Abstract

© 2021 Soc. for the Advancement of Material and Process Engineering. All rights reserved.For the current study, Fiber Metal Laminates (FML) in the form of Glass Laminate Aluminum Reinforced Epoxy (GLARE) and an aluminum honeycomb have been used to construct sandwich structures. Dynamic values of the structures have been measured using a non-contact vibrating beam test with free-free end conditions. A numerical modal analysis via the Altair Hyperworks 2019 Software has also been conducted. The results from the experimental and numerical works have been found in a good agreement. The effects of different fiber orientations of the laminates on the fundamental natural frequency, equivalent flexural modulus and especially damping values of the sandwich structures seem considerable.
