“…Sitnikova et al [13] employed a finite element analysis to study the perforation failure of FMLs subjected to high-intensity blast impact loading. The results were validated against the experimental results of Langdon et al [19]. Sitnikova et al [13] found that their finite element model captured most failure modes of the FMLs under high strain rate loading, such as 'petalling' (where petalling is defined as the metal alloy tearing and being plastically deformed around a perforation hole to form petal-shaped features), fracture of the composite layers and multiple delaminations of the metal/composite interfaces.…”

“…In an experimental study, Langdon et al [19] performed localised impact blast tests on thermoplastic-based FMLs, made of glass-fibre-reinforced polypropylene and relatively thick layers of aluminium alloy (Grade 2024-O). In this study, various types of FMLs were explored by changing the number of aluminium alloy and composite layers, with the total aluminium alloy volume fraction varying from ca.…”

“…Damage and failure modes involved multiple delaminations, largescale plastic deformation, fibre fracture and matrix cracking. Using the experimental data of Langdon et al [19], Lemanski et al [20] determined an analytical expression for the critical impulse for the onset of tearing this, and this was found to increase linearly with the thickness of the FML. (Tearing, in the context here, is defined as the plastic fracture of the rear aluminium alloy layer [i.e.…”

The quasi-static flexural and impact performance, up to projectile impact velocities of about 270 m s -1 , of fibre metal laminates (FMLs), which consist of relatively thin, alternately stacked, layers of an aluminium alloy and a thermoset glass fibre epoxy composite, have been investigated. The effects of varying (a) the yield strength, tensile strength and ductility of the aluminium alloy layer, (b) the surface treatment used for the aluminium alloy layers and (c) the number of layers present in the FML have been studied. It was found that increasing the strength of the aluminium alloy increases the quasi-static flexural strength of the FML, providing that good adhesion is achieved between the metal and the composite layers. Further, increasing the number of alternating layers of the aluminium alloy and fibre composite also somewhat increases the quasi-static flexural properties of the FML. In contrast, increasing the strength of the aluminium alloy had relatively little effect on the impact perforation resistance of the FML, but increasing the number of alternating layers of aluminium alloy and fibre composite did significantly increase the impact perforation resistance of the FML. The degree of adhesion achieved between the layers had only a negligible influence on the impact perforation resistance.

Abstract:In this paper, a multi-layered composite inspired by the hierarchical structure of nacre and made of layers of aluminium alloy AA 7075 bonded with toughened epoxy resin is introduced for blast resistant applications. The performance of the proposed nacre-like 3.3-mm and 5.4-mm thick composite plates, made of 1.1-mm thick AA 7075 layers, under localised impulsive loading was numerically studied. The epoxy material was modelled using user-defined interface cohesive elements that properly take into account both strength and toughness enhancements under compression. As compared to bulk plates, the improvement in blast resistance performance was numerically observed in the nacre-like plates, which required larger loads to reach the onset of failure. In addition, a reduction of the peak velocity and maximum deflection of the back face was observed for the nacre-like plates. This improvement is explained by the hierarchical structure facilitating a globalized energy absorption by inter-layer interlocking, delamination and friction.
