On impact behavior of fiber metal laminate (FML) structures: A state-of-the-art review

Fiber metal laminates (FMLs) comprised of metal alloy and composite materials have been extensively applied in a broad range of engineering structures in virtue of their outstanding functional characteristics and cost benefits. This paper provides a comprehensive review on the state-of-the-art of the impact characteristics of fiber metal laminates through experimental, numerical and analytical methods. First, influences of various internal and external factors/parameters on the impact responses and damage mechanisms of fiber metal laminates are discussed in detail for different impact conditions. Second, a range of numerical techniques are compared to evaluate their effectiveness for modeling the impact behavior of fiber metal laminates as reported in literature. Third, analytical models and associated engineering applications of fiber metal laminated structures are also discussed. Based upon the material constituents and manufacturing techniques, some feasible methods are suggested to enhance the impact resistance of FML materials. Finally, the concluding remarks and outlooks are provided for recommending the potential future studies on novel FML materials and structures.
