“…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.…”

“…FMLs have been the subject of many studies over a wide range of loading conditions including quasistatic bending and indentation [11,12], blast loading [13], low-velocity impact [14] and high-velocity impact [15]. For example, Reyes and Cantwell [16] have conducted uniaxial tensile tests on thermoplastic-based FMLs, consisting of layers of aluminium alloy and glass-fibre-reinforced polypropylene.…”

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.

“…Since Hashin failure criteria is applicable for unidirectional (UD) lamina, the woven composite lamina was modelled by defining independent material orientation by [0/90] UD pair. Sitnikova et al [25] improved the composite failure criteria with a set of quadratic based tension-shear and compressive failure criteria for weft and warp fibre directions of woven lamina in their FE model. Good agreements with published experimental damage shapes had proven the ability of a user-defined woven fabric failure model.…”

The present paper gives details of the structural response of titanium-based fiber metal laminates (TFML) subjected to high velocity impact. Dynamic perforation behavior of two different sample configurations, TFML-2/1 and 3/2 are presented. The behavior of the metal and composite layer is defined using two independent appropriate constitutive material models. Both experimental and numerically predicted residual velocity follows the Recht-Ipson model variation with impact velocity. Being larger in thickness, residual velocity, peak contact force and total energy absorbed were found to be larger for TFML-3/2 than 2/1. However, the contact duration was rather insignificantly affected. Having similar metal volume fraction (MVF), energy dissipated by means of plastic deformation of metal layers was found to be constant for both TFML configurations that were considered. The axisymmetric loading, boundary conditions and having balanced material property distribution along the principle axes resulted in doubly symmetric damage surfaces, both layer-wise and overall. The developed finite element (FE) model adequately simulated the contact behavior and all of the experimentally realized damage modes in the metal and composite layers and confirmed its reliability. Having limited experimental information, the obtained numerical information allows one to briefly understand the dynamic perforation behavior of TFML laminates.

“…In recent years, a number of studies were performed to investigate the impact resistance of FMLs under different loading conditions.Mugica et al analyzed the impact induced penetration and perforation behaviors of a2024-T3 aluminum-based fibre metal laminate under low-velocity impact tests (Múgica et al, 2014). Sitnikova et al investigated the perforation failure of FMLs panels subjected to the localized high intensity blast loading (Sitnikova et al, 2014). Different from previous studies, the impact effect induced by LPF is a non-contact process generated by pulsed-laser induced shock pressure to bend the FMLs materials without expecting any failures.…”
