Numerical studies of the low velocity impact behaviour on hybrid fiber metal laminates

Abstract

Abstract The Fiber metal laminates (FML) are the advanced composites that comprise the property of metal and FRP layers. FMLs are used for the manufacturing of fuselage skins, Cargo floors and the leading edge of aircraft etc. In this paper, Explicit Finite element method used for the simulation of low velocity impact behaviour on the fiber metal laminates. The FML with glass fiber (GFML) and FML with hybrid (Carbon + Glass) fiber (HFML) have been considered for the simulation. The Johnson-Cook material model is used to model the plasticity and damage of the Aluminium layer. Hashin Damage criteria were used for the FRP layers. Comparison of Force-Time and Force- Displacement histories are carried out. From the studies it is found that Carbon and Glass fiber based HFML are superior compared to the GFML.
