“…Complex solutions using metals, ceramics, and polymers have been described in several publications [1][2][3]5]. Also, the authors of this work took up the subject of layered composites as ballistic shields [1,4]. The topic of metallic foams as layers in composite armour, including their ballistic effectiveness, was described, among others, in the works of Garcia-Avila et al [2,6] as well as other authors [3,7,8].…”

In recent years, hybrid composite materials are of increasing interest during the search for new materials to be used as ballistic barriers (shields) and kinetic energy absorbers. The main objective of this study is to test the energy absorption capacity of Zn-Al alloys filled with various polymer materials (epoxy resin, polyurethane resin and silicone). The ballistic resistance of modern hybrid materials to direct firing of a 5.56 × 45 mm SS109 projectile and during quasi-static piercing test is examined. Next, a numerical simulation in the ABAQUS environment is performed. In order to accurately reproduce the foam structure, a computed microtomography (CT) system is used. In the simulation of deformations of viscoplastic bodies, the Lagrange and Smoothed Particle Hydrodynamic (SPH) methods are applied. The obtained results from numerical analyses are verified with experimental results. Metallic foams are proven to have only a remote influence on the impact load, while, when filled with polyurethane resin, they show resistance to the overshoot. Performed simulation supports the detailed analysis of the impact energy dissipation for each of the samples.

“…The results of tests conducted to determine the exposure of crew and special equipment to hazards such as direct fire, shrapnel, anti-tank mine blast or improvised explosive device have been presented in [22,33]. This approach allows to develop solutions offering improved protection [24,27,28] and parametric optimisation [34] to minimise crew exposure as much as possible. Compliance with international requirements, such as NATO STANAG 4569, is another important aspect to consider in the design process.…”

On the battlefield, modern vehicles perform a variety of roles. Transportation is one of the most fundamental. Operating in different terrains, including urban areas, means exposing the crew to different hazards. To increase crew protection, passive and active protection systems are used. On the other hand, in addition to protection, support of the infantry in offensive operations is an equally important activity. The most common solution for medium wheeled vehicles is a manned turret. The weapon is a 30 mm cannon. Nowadays, there is a trend towards installing systems that allow such weapons to be operated remotely. This minimises the exposure of highly trained personnel. This paper presents the results of a numerical study of the dynamic loads on the roof-plate structure of a wheeled armoured personnel carrier resulting from the firing of the vehicle's main armament. It includes the values of the strains and stresses in the upper plate structure and the forces transmitted by the brackets connecting the roof plate to the bottom plate, and an assessment of the risk of using such a system on the safety of the vehicle structure and its crew.

“…In [3,4], tests were carried out to determine crew and special equipment exposure to hazards such as direct fire, shrapnel, explosion of anti-tank mines, or improvised explosive devices. As a result, this approach allows for the development of solutions providing improved protection [5][6][7][8] and parameter optimisation [9] in order to minimise crew exposure as much as possible. Another important aspect to be included in the design process is compliance with international requirements, such as the NATO STANAG 4569.…”

Research of Vibrations of an Armoured Personnel Carrier Hull with FE Implementation

Modern wheeled armoured vehicles can perform a variety of tasks, making the development of weapon systems that can be safely and effectively integrated with the vehicle structure an area of interest. Due to the cost of implementing new models, it is more economical to test potential configurations using numerical methods, such as the finite element method. The numerical model has been validated to confirm the reliability of the obtained results. Modal tests were also performed using four configurations to identify the frequency and mode shape of natural vibrations occurring within the support structure. In an experimental setting, hull vibrations were forced using the modal hammer testing method. The modal assurance criterion (MAC) and the authors’ procedure were used to confirm the experimental and numerical test results. Additional testing in the form of impact loads was carried out for turret-containing structures. Structural strain at indicated points and forces transmitted by brackets to the bottom of the hull were compared.
