In the present research, glass and basalt fiber-reinforced polypropylene composites’ behaviour in quasi-static dynamic conditions is studied. Composites were fabricated by vacuum assisted Compression molding method. failure under tension compressive was studied along with its low-velocity impact super-sonic shock loading conditions. The study results showed that (Basalt/PP) composite’s tensile strength higher than (Glass/PP). Basalt/PP no penetration against low velocity (LVI) negligible...
Safety of defense and paramilitary operators in hostile environments can be ensured by using ballistic materials. Various destructive non-destructive techniques are available for characterizing materials performance respective products but they expensive protracted. Finite Element method (FEM) is useful these situations as it used during design phase to determine critical sections material products. This study focuses on FE simulation ARMOX armor steel blast protection anti-land mine...
Abstract Material systems capable of handling both the ballistic impact and blast waves are necessary for security forces. In this study, high strain rate performance monolithic bonded ultra‐high molecular weight polyethylene (UHMWPE) with high‐temperature resistant basalt/polyetherimide (B/PEI) composite is presented. Individual laminates were fabricated using vacuum‐assisted compression molding. Subsequently, cylindrical test coupons cut a high‐pressure waterjet. A suitable adhesive grade...
Shock tube experiments were carried out to investigate dynamic behavior of Ultra-high hardness (UHH) steel and Aluminium (Al) sheets 0.8 mm thickness at 0.55, 0.9 1.18 MPa peak-over pressure. Experimental results showed that center point deflection increases with an increase in pressure for Al sheets. However, UHH negligible deformation when loaded low pressures sudden brittle failure high pressures. Similar obtained by quasi-static testing, failed abruptly while ductile behavior. Results...
Adhesives are viscoelastic polymeric materials with rate-dependent behaviour. A personal body armour for higher threat perception consists of hard ceramic facing adhesively joined to a composite laminate backing. This work focuses on the mechanical testing two types adhesive materials, i.e., epoxy-based and polyurethane-based by bonding dissimilar understand their role in protection against ballistic impact. Block shear tests were conducted at various thicknesses adhesives layer. Epoxy-based...
The presented study investigates the effect of moisture absorption on compressive high strain rate performance Ultra High Molecular Weight Polyethylene-Synthetic Rubber composite along thickness direction. Split Hopkinson Pressure Bar is employed to investigate dynamic properties. cylindrical test specimens were machined from flat laminate fabricated by compression molding. Two types used for testing. First set specimen was oven dried at 65°C and second dipped in potable water as per NIJ...
The purpose of this work is to study the applicability Polycarbonate (PC)/ Methyl acrylate (MA) blend and their nanocomposites as a matrix based on high strain rate behaviour. dynamic mechanical experiments have been performed using Split Hopkinson Pressure Bar (SHPB) all prepared PC/MA MWCNTs reinforced nano-composites. Toughness at yield has shown huge improvement after blending neat PC. peak stress increased 24 % limiting 11514 /s 55 13252 for nano-composite, respectively. During testing,...
Shear Thickening Fluids (STFs) are a special class of field responsive non-Newtonian fluids which exhibit transition from low viscosity to high state when they subjected shearing deformation above the critical shear rate (CSR). Due this unique characteristic STFs, these have found application in ballistics, especially development body armors called Liquid Body Armors (LBAs) lighter weight and more flexible as compared conventional heavy armours. Fumed silica (FS) is rheologically significant...
Despite its relevance for law enforcement applications, the design of soft armor has mainly been based on a trial-and-error approach. In this paper, combined experimental, machine learning, and finite element analysis framework is used to build predictive numerical model hence, armor. The material models major components certification system—bullet, shoot pack, straps, clay backing, are first constructed using laboratory tests publicly available data. Next, three metrics, namely, back face...
Object tracking at dark is critical to minimizing the number of nocturnal traffic crashes. This paper presents a deep convolutional neural network dubbed M-YOLO enhance precision object recognition and be suited for limited contexts (also including microcontrollers in automobiles). To begin, track line images are separated into other * 2S panels based on features uneven spatial temporal dispersion densities. Additionally, sensor frequency has been four measurement levels, making it even more...
