“…However, studies have shown that their mechanical properties are altered after being remelted and reformed, limiting their re-usability to around 10–15 times. 81,82 Recently, researchers opted for polymer-based gels like Styrene-Ethylene-Butylene-Styrene (SEBS) as an alternative to ballistic gelatin. SEBS gels were thermoplastic elastomers and offered comparable performance characteristics.…”

Human surrogates have long been employed to simulate human behaviour, beginning in the automotive industry and now widely used throughout the safety framework to estimate human injury during and after accidents and impacts. In the specific context of blunt ballistics, various methods have been developed to investigate wound injuries, including tissue simulants such as clays or gelatine ballistic, physical dummies and numerical models. However, all of these surrogate entities must be biofidelic, meaning they must accurately represent the biological properties of the human body. This paper provides an overview of physical and numerical surrogates developed specifically for blunt ballistic impacts, including their properties, use and applications. The focus is on their ability to accurately represent the human body in the context of blunt ballistic impact.

“…This encourages manufacturers to develop new means of protection. After all, on the one hand, the destruction of elements of tactical equipment disorients the soldier on the battlefield, and on the other, the hit of a "usable fragment" into the socalled "non-vital part of the body" does not guarantee the survival of the serviceman [37]. Thus, in the case of penetration of a fragment-embolus through one of the walls of the lower half of a vein with blood flow, it migrates to the heart.…”

The problem of determining the components of the structural-automatic model is solved by creating a graph of states and transitions. The purpose of the process is to form a formalized expression of the object of study in the form of a structural-machine model of the process of firing a mobile armored vehicle with a series of three shots with fragmentation-beam projectiles of directional action. This model can be further practically implemented during the development of the latest samples of fire resistance in order to reduce errors at the stage of system design. This approach reduces the cost of design and production of prototypes by up to 25 %. This paper considers the process involving interrelated elements of the components of a system while accounting for all possible variants of its behavior from the moment of detection to the failure of a single target in armor protection to perform tasks as intended. The execution of a fire task is considered as a set of certain procedures characterized by the average value of their duration. The explosive destruction of the hull of each fragmentation-beam projectile is characterized by the self-propagation of the reaction of explosive transformations based on tabular data on an armored combat vehicle. Appropriate procedures (phases) of firing a single target in armor protection are advisable to formalize to create preconditions for obtaining the value of a statistical indicator of the effectiveness of causing damage to the target and to study further alternative options for this process. For the proposed structural-automatic model of the process of firing a single target in armor protection with a series of fragmentation-beam projectiles of directional action, validation and verification were carried out, which demonstrated the convergence of the results that exceeded 60 %. The use of the structural-automatic model's components proposed in this work increases the probability of performing a fire task for the first shot from 0.23 to 0.88, for the second – from 0.35 to 0.95, for the third – from 0.45 to 0.98

“…Functional body armor must, in general, deflect a ballistic projectile and release the kinetic and momentum energy that was transmitted through the shielding. 1 Prior to a ballistic bullet entering the body and potentially injuring someone, its energy and motion must be dissipated. As a result, less impact energy passes through the shield and the energy density of the bullet is reduced at the area of impact, leading to deformation in the armor's back.…”

In this study, the usability of several composite plates in level III and level IV body armors were examined, along with the ballistic resistance, protection level, and production parameters of each plate. For level III protection, composite panels are made using the heat pressing method under various pressures, and for level IV composites, ceramic plates of various thicknesses are reinforced on the back with various composite materials. Ballistic tests using the NIJ standards were performed on the created composite panels. There were delaminations between the layers as a result of the ballistic test in the level III protective panels produced at 140 bar pressure, but there was no puncture in the panels produced at 250 bar pressure, and the depth of trauma was reduced to a minimum. These observations were made using samples produced at 90 bar pressure under controlled conditions. Level IV panels were subjected to dry and wet ballistic tests, and the results of these tests showed that K-flex reinforced ceramics were impervious to punctures. It has been found that aramid-reinforced epoxy ceramic panels and UD H62 reinforced ceramics have superior ballistic qualities and are 6% lighter.
