Finite element modeling of ballistic impact inserts containing titanium structures were presented in the article. The an additional layer made using additive manufacturing technology analyzed. was created from repetitive elements without connections (adjacent cells inseparable). Four variants printed placed between layers Twaron CT 750 aramid fabric to create inserts. In order assess resistance inserts, numerical simulations phenomenon carried out LS-Dyna software. on a steel box filled with...
This article presents an analysis of the effectiveness available numerical techniques in mapping characteristic behavior ballistic ceramics under projectile impact conditions. As part work, tests were performed on layered ceramic/steel composite armor and tested with 7.62 × 39 mm, armor-piercing incendiary (API) BZ projectile. The experimental then mapped using computer simulations. In analyses, four different used to describe cubic ceramic tiles Al2O3 placed ARMOX 500T steel backing plate,...
ABSTRACT The paper analyzes the issues relating to applicability of innovative material systems for flexible composite armors. authors made several samplings aramid fibers (Kevlar 49) by replacing epoxy resin base, which is often described in literature, with thermoplastic matrix - polyethylene (HDPE) and polypropylene (PP). samples were fired .38 Special Full Metal Jacketed (FMJ) ammunition produced S&B Company, then process firing was modeled ABAQUS program. advantages...
This paper discusses the general conditions relating to ballistic head protection, analyzing risks that may occur on contemporary battlefields. A thorough literature review has enabled us present development trends for helmets used in largest armies world. The authors have focused impacts helmet shell, overloading entire helmet-protected head–neck system. main objective of this study is investigate protective capability a shell when subjected projectile–helmet contact, with contact curvature...
The friction behavior of the formed antifriction films and their effect on functional properties composite based powder nickel alloy EI929 with solid lubricant CaF2 at high temperatures was investigated. An film contact surfaces during process. Such a result interaction atmospheric oxygen temperatures.

The paper presents the results of studies on effects shooting composite materials produced by pressure infiltration with EN AW-7075 alloy as a matrix and reinforcement in form preforms made α-Al2O3 particles. Composite were two contents (i.e., 30% 40% vol. particles). composites 12 mm thick plates subjected to impact loads from 7.62 × 39 FMJ M43 projectile fired Kalashnikov. samples different strengthening particles detailed microscopic examination determine mechanism destruction. effect...
In this paper, the authors presented an analysis of strengthening cumulative jet by appropriate formation detonation wave front acting under influence high pressure on liner. The Polish ŁK charge was carried out using numerical methods in ABAQUS program. Simulation studies were axial and peripheral initiations explosive For purpose, two types charges made with same design parameters, differing only detonation-initiation system. impact elastomer insert focusing verified. initiation a jet’s...
The research involved analyzing a material solution for 9 mm Full Metal Jacket (FMJ) Parabellum loaded with ballistic impact on resin laminate strengthened extra aramid layers. goal of this is to determine the (aramid/DCPD) layer thickness energy absorption performance blunt trauma as criterion (BC). For purpose, fiber dicyclopentadiene (DCPD) matrix was prepared. Laminate samples were tested drop test and subjected loads. ABAQUS/Explicit program finite element method used conduct study....

The dissipative properties of most structural materials are usually described by a viscous damping parameter determining the rate energy dissipation. stem from traditionally adopted rheological Kelvin model. However, analytical description dynamic modern materials, including biological often poses difficulties, due to fact that stress–strain dependence in these is not linear. Therefore method nonlinear form characteristic $$ D\left( {x,\dot{x}} \right) (is presented. As it assumed,...
Research for innovative composite material solutions impact absorbers is focused on the analysis of their ability to absorb energy. For this purpose, aramid fiber laminate with DCPD resin matrix was prepared. Laminate samples were tested drop test and subjected ballistic loads. The structure modeled ABAQUS software objective optimize estimate energy in range high speeds (350m/s).
This paper presents numerical examination of cermet-type composite material subjected to impact loads.
