Abstract

© 2021 Soc. for the Advancement of Material and Process Engineering. All rights reserved.Owing to their high fatigue life and energy absorption capabilities, Glass Reinforced Aluminum Laminate (GLARE) hybrid systems are the most preferred type of the Fiber Metal Laminate (FMLs) that have been the focal point of many works conducted at high stress levels. In this study, dynamic performance of a GLARE was investigated at low stress levels using a vibrating beam technique with fixed-free end conditions. Effects of different glass fiber angles of plies on the GLARE material were evaluated with a special emphasis on the damping values. Values of equivalent flexural modulus of the specimens were measured experimentally and compared with the predicted ones that were obtained via a numerical modal analysis. The results from both methods are reasonably in a good agreement.
