“…They reported good agreement between resulting failure modes, maximum permanent displacement and decay of the kinetic energy of the projectile with experimental results. Song et al [24] modeled carbon reinforced aluminum laminates (CARALL) under low velocity impact using ABAQUS software. They used shell element with Hashin's failure criterion for the composite layers and 8-node solid element without failure criterion for the aluminum alloy.…”

“…Both shear and tensile failure criteria were used to simulate the failure processes in the aluminum layers and a similar tensile failure criterion used for the composite layers. The second approach [24] used 8-node solid element (C3D8R) and 8-node shell element (SC8R) for the aluminum alloy and composite layers, respectively. In the implemented model, the Hashin damage initiation criteria were used for the composite layers and no damage criterion was applied to the aluminum sheets.…”

“…The second approach [24] was also adopted, which differs from the first approach in the element and failure criterion selection for composite layer; here 8-node continuum shell elements (SC8R) applying the Hashin damage initiation criteria was used. Although in ref [24], solid elements (C3D8R) were applied for aluminum alloy without any failure criterion, the present research used similar assumptions for aluminum as the first approach, i.e.…”

“…The discrepancies between FE-predictions and experimental results are more evident for the Mg-GL5 laminates, since great amount of fracture occured within the laminates at relatively high impact energy. However, it is shown that the FE-model, which requires less computer time compared to the complex model (third approach [24]), is capable to predict overall behavior of FMLs under impact loading with sufficient accuracy. …”

The impact response of fiber metal laminates (FMLs), has been investigated with experiments and numerical simulations, which is reported in this article. Low-velocity impacts were carried out to study the effects of metal type and thickness within FMLs. Glare5-3/2 laminates with two aluminum layer thicknesses and a similar FML containing magnesium sheets were impacted by drop weight tests. Also, a major part of this study was to accomplish a dynamic non-linear transient analysis to study the impact response of FMLs using the commercial finite element (FE) analysis code ABAQUS. By reviewing different approaches of modeling constituents of an FML, it is shown that the appropriate selection of elements has more significant role than failure criterion to predict acceptable results for this type of laminate and loading. The good agreement obtained between experimental and numerical results verifies the possibility of relatively simpler simulation by FE-analysis to predict overall response of FMLs under impact loading.

The comparison of low‐velocity impact resistance of aluminum/carbon and glass fiber metal laminates

This article presents the low-velocity impact response of fiber metal laminates, based on aluminum with a polymer composite, reinforced with carbon and glass fibers. The influence of fiber orientations as well as analysis of load-time history, damage area and damage depth in relation to different energy levels is presented and discussed. The obtained results made it possible to determine characteristic points, which may be responsible for particular stages of the laminate structure degradation process: local microcracks and delaminations, leading to a decrease in the stiffness of the laminate, as well as further damage represented by laminate cracks and its perforation. The damage mechanism of fiber metal laminates is rather complex. In case of carbon fiber laminates, a higher tendency to perforation was observed in comparison to laminates containing glass fibers. Delaminations in composite interlayers and at the metal/composite interface constitute a significant damage form of fiber metal laminates resulting from dynamic loads. Fiber metal laminates with glass fibers absorb energy mainly through plastic deformation as well as through delamination initiation and propagation, whereas laminates containing carbon fibers absorb energy for penetration and perforation of the laminate.

A detailed experimental investigation was carried out for the high‐velocity ballistic response of AA 1100‐H14 based carbon‐fiber metal laminates (FMLs). FMLs with different metal volume fractions and the same thickness of carbon‐epoxy fiber laminates were tested to examine the surface and internal damage. The ballistic performance parameters, namely % escalation in absorbed energy, specific energy absorbed, ballistic limit, specific perforation energy, first cracking energy, and global deformation profile, were studied and a comparison was drawn with pure carbons fiber reinforced epoxy composite laminates. Despite having greater thickness, pure carbon fiber‐reinforced epoxy composite laminates absorbed less impact energy than FMLs and failed catastrophically. For FMLs, the % escalation in the absorbed energy and the specific energy absorption kept increasing with the increasing impact velocity until the onset of perforation. Once the perforation started, both these parameters showed a decreasing trend. Thick FMLs absorbed a good amount of energy, leading to projectile recoil suffering minimal damage. The ballistic velocity, specific perforation energy, and first cracking energy on the front and rear face of FMLs layers showed an increasing trend. The minimum for the thinner and maximum for the thicker FMLs attributed to the large thickness and more metal volume fraction. Contrary to the large deformation of the impacting points, pure carbon fiber‐reinforced epoxy composite laminates showed very minimal deformation as compared to FMLs. The brittle nature of the epoxy resin resisted the deformation to a large extent leading to less energy absorption.Highlights High‐velocity ballistic response of AA 1100‐H14 based carbon‐FMLs was investigated. Ballistic performance parameters of FMLs were studied and was compared with carbons fiber reinforced composite laminates. The ballistic limit of FMLs showed a direct dependence its thickness and metal volume fraction. In the absence of any metallic layer, pure carbons fiber reinforced composite laminates absorbed less impact energy.
