“…Thus, the mechanical response of such structures under dynamic loading conditions and high strain rates is vital from the aspect of engineering design. The high strain rates for the ballistic and blast impacts reach >(10 − −10 4 s −1 ) [15][16][17][18][19] . Typical construction of fiber-metal laminates include metallic/ alloy skins stacked alongside fiber reinforced polymer laminae 6,[20][21][22][23] .…”

An experimental investigation on the effect of incorporating graphene nanoplatelets on the low-velocity impact behavior of fiber metal laminates

“…It was found that the FMLs had a much higher resistance than aluminum and composite layers against impact, also by comparing the FML types (ARALL, CARALL and GLARE), they concluded that GLARE had better impact properties and was able to absorb more energy [7][8][9]. After Vlot, during the last two decades, numerous researches have been performed to examine the impact behavior of the FMLs considering the effect of various parameters and factors, such as layup configuration [10][11][12][13][14][15][16], metal constituents [10,[17][18][19][20][21][22][23], distribution of layers [24][25][26], thickness effect [19,[27][28][29], impactor geometry [30][31][32], strain rate [33][34][35][36],repeated impact response [1,[37][38][39][40] and damage area [26,41]. Additionally, Jakubczak et al [42] evaluated the FML damage mechanisms at low energy impacts and reported that matrix fractures (at the fiber/matrix interface), fiber cracking, and delamination were the main modes of damage.The low-velocity impact damage is an important failure pattern in FML structures and complex damage modes make it more challenging to characterize the low-velocity impact be...…”
