“…From the figures, we observe a perforation of front skin and deformation of core without intrusion in the rear skin; where the projectile is embedded on deformed core. Accordingly, the same conclusion behavior was resulted from the experimental work of Arslan and Gunes [10]. We mention that the diameter hole created in the front skin is about 19.7 mm.…”

In this paper, our analysis concentrated on the mechanical behavior of sandwich panel subjected to impact loading. Thus, to improve the resistance of satellite structures from debris collision consequences; we proceed a performance investigation numerically of different materials based on the evaluation of contact force, total energy and kinetic energy generated from the impact of spherical steel debris on sandwich panel. Furthermore, a comparison of deformations and stresses levels in sandwich panel collide by a projectile at hyper-high velocity using finite element with ANSYS code was made. The difference between our models is the type of skins materials which are aluminum and functionally graded material FGM (alumina/ nickel). The impact results a total perforation of sandwich panel with aluminum facesheets creating a fragments; contrary to FGM which the projectile penetrates only the front facesheet and honeycomb core. However, for an effective protection of sandwich panel against debris perforation, the introduction of FGM skins technique is considered as a candidate solution.

“…A few researcher had used FGM as a reinforcement of skins honeycomb panel. Thus, Arslan and Gunes [10] conducted an experimental impact assessment of sandwich honeycomb panel with aluminum and FGM facesheets at high velocity; thus, for FGM five types are considered by changing index power law.…”

“…Honeycomb sandwich structures have very low weight, high stiffness, and strength [7] which make them applicable in many industrial fields such as high-speed ground and air vehicles, shipbuilding and so on [8,9]. Due to the widespread usage of these structures, many researchers have carried out experimental investigations to realize the mechanical response of honeycomb sandwich panels composed of different skins and core materials under various loadings [10][11][12]. One of the most important loading condition is impact loading, which usually occurs at high velocities.…”

The employment of lightweight structures is one of the most important goals in various industries.The lightweight sandwich panel is an excellent energy absorber and also a perfect way for decreasing the risk of impact. In this paper, a numerical study of high-velocity impact on honeycomb sandwich panels reinforced with polymer foam was performed. The results of the numerical simulation are compared with experimental findings. The numerical modelling of high velocity penetration process was carried out using nonlinear explicit finite element code, LS-DYNA. The aluminum honeycomb structure, unfilled honeycomb sandwich panel, and the sandwich panels filled with three types of polyurethane foam (foam1: 56.94, foam2: 108.65 and foam3: 137.13 kg/m 3 ) were investigated to demonstrate damage modes, ballistic limit velocity, absorbed energy, and specific energy absorption (SEA) capacity. The numerical ballistic limit velocity of sandwich panels filled with three types of foam were more than the bare honeycomb core and unfilled sandwich panel. In addition, the numerical results show that the sandwich panel filled with the highest density foam could increase the strength of sandwich panel and the numerical specific energy absorption of this structure is 23% more than unfilled. Finally, the numerical results were in good agreement with experimental findings.

The analysis of ballistics resistance of a combined metal-ceramic material based on high-strength ceramics in conjunction with the intermetallic on high strength metallic substrate layer – (TiB2+NiTi)+Ti in comparison with the steel plates, the titanium alloy BT1-0 plates and the corundum ceramics plates under impact with the steel spherical striker in velocity range about 2500 m/s was carried out. An experimental researches of protective barriers under the high-speed impact were carried out on the high-speed ballistic experimental facility. A mathematical modeling for the porous elastoplastic medium with taking an account various mechanisms of materials disruptions which was modified for mediums with complicated composition was carried out. There is shown, under the considered impact velocity range at breaking through barriers, in spite of low superficial density, a material (TiB2+NiTi)+Ti shows more force impact on the striker and greater penetration resistance then the steel, the titanium and the ceramics.
