Finite element analysis of dynamic response of fiber metal laminates (FMLs)subjected to low velocity impact

Fiber–metal laminates (FMLs) are high-performance hybrid structures based on alternating stackedarrangements of fiber-reinforced plastic (FRP) plies and metal alloy layers. The response of FMLssubjected to low-velocity impact is studied in this paper using finite element analysis. The aluminum(Al) sheets are placed instead of some of layers of FRP plies. In this research, the effects of differentaluminum layer position, various impactor mass, and disparate impactor velocity have beeninvestigated. The results showed that by increasing both impactor mass and impactor velocity, themaximum contact force increases. Furthermore, in different Al layer position used in FML plate, whenthe positions are further than the mid-plane of the FML plate, the contact force value is higher.
