Due to the increasing cost of experiments and the increased time required to complete the experimental process, it is more economical to conduct experiments in the form of virtual tests. Therefore, low velocity impact simulation was carried out on fiber metal laminates, FMLs with an impactor with various weights in our study. LS-DYNA software was selected to perform the simulation. Fiber metal laminate is composed of 2024-T3 Aluminum and Glass/Epoxy layers. The layers are modeled as isotropic, and anisotropic material. The stacking sequence of FML is (Al/0/90/Al). Two opposite sides of the square shaped FML are fixed and the other sides are left free. Steel strikers with masses of 0.15 kg, 0.30 kg and 0.45 kg were used in the analyses, respectively. The speed of the striker at first contact with the FML is 10 mm/ms. As a result of the tests, force-time, force-displacement, velocity-time and energy - time variations were also obtained. The results were presented as graphs. It has been found that the FML structure absorbs an average of 73.4% of the impact energy because of the low-velocity impact, thus preserving the integrity and functionality of the designed structure. Thanks to such numerical experiments carried out before production, the mechanical properties of the designed structure can be evaluated.
