“…Bikakis investigated the low-velocity impact of circular GLARE FMLs using linearized spring-mass model. He presented an analytical expression to predict the impact load, position and velocity time history and compared the predicted results with those of experiments [25]. Morinière et al developed a progressive quasi-static model to predict dynamic response of GLARE subjected to low-velocity impact.…”

This paper investigates the eccentric low-velocity impact of Fiber metal laminates (FMLs) subjected to spherical projectile using a unified ZigZag plate theory. The presented zigzag plate theory enforces transverse shear stress continuity through the thickness and can be reduced to conventional plate theories using appropriate shape function. The governing equations and suitable boundary conditions are obtained using the principle of minimum total potenital energy. Runge-Kutta method is employed to solve initial value problem resulted by the method of Ritz. The present model is validated by comparison and good agreement between its results and those of reports in open literature. Influence of various specifications of impact phenomenon such as laminate thickness, projectile radius, projectile velocity, in-plane load and eccentricity parameter is examined on deflection and contact force time history. The obtained results indicate that continuity of transverse shear stress is required to achieve accurate contact force even for moderately thin FMLs.

“…Nevertheless, many phenomena are still developed by implementing various boundary conditions and displacement functions [11,12]. An analytical point of view plays a significant role in final results analysis and such considerations were made by Bikakis [34,35,36,37,38] who tried to predict the behavior of GLARE circular plates under the influence of low-velocity impact effect. Impact was simulated by the support of impactor with hemispherical tip [26,39] with constant radius and circular GLARE plate with defined dimensions [34].…”

The paper refers the general idea of composite materials especially Fiber Metal Laminates (FMLs) with respect to low-velocity impact incidents. This phenomenon was characterized by basic parameters and energy dissipation mechanisms. Further considerations are matched with analytical procedures with reference to linearized spring-mass models, impact characteristics divided into energy correlations (global flexure, delamination, tensile fracture and petaling absorbed energies) and set of motion second order differential equations. Experimental tests were based on analytical solutions for different types of FML - GLARE type plates and were held in accordance to ASTM standards. The structure model reveals plenty of dependences related to strain rate effect, deflection represented by the correlations among plate and intender deformation, separate flexure characteristics for aluminium and composite, contact definition based on intender end-radius shape stress analysis supported by FSDT, von Karman strains as well as CLT. Failure criteria were conformed to layers specifications with respect to von Misses stress-strain criterion for aluminium matched with Tsai-Hill or Puck criterion for unidirectional laminate. At the final stage numerical simulation were made in FEM programs such as ABAQUS and ANSYS. Future prospects were based on the experiments held over 3D-fiberglass (3DFG) FMLs with magnesium alloy layers which covers more favorable mechanical properties than FMLs.

“…[10][11][12][13][14][15] A well-known example of a fibre-metal-laminate is GLARE, where glass fibre-reinforced epoxy layers and aluminium sheets are used. [16][17][18][19][20] In contrast, the present study is focussed on the usage of thermoplastic matrix materials, which offer significantly more energy absorption than thermosets, and thus are preferably used for impact-specific laminates. [21][22][23] In contrast, the adhesion of thermoplastic matrix materials to metals is often lower than those of thermosets.…”

The combination of thin light metal sheets with fibre-reinforced thermoplastic layers in multi-layered fibre-metal-laminates advantageously combines the properties of both material classes. In this way, components can be developed which have both significantly increased specific properties (strength and stiffness with respect to density) and high energy absorption capacity compared with conventional design with mono materials. However, the structural behaviour of crash structures is decisively determined by material behaviour of the thermoplastic and metal constituents as well as the interface properties between both constituents and the corresponding delamination behaviour. To evaluate the structural response of multi-layered fibre-metal-laminates under highly dynamic loading conditions, Charpy tests were performed, where the test parameters, light metal material configuration, support length and laminate thickness, were varied. Moreover, the metal sheet surfaces were pre-treated by embossing to achieve different surface topologies. The influence of the different test parameters on the specific energy absorption capacity was characterised by the analysis of force–displacement curves.
