International Journal of Intellectual Advancements and Research in Engineering Computations www.ijiarec.com ISSN:2348 -2079 Volume-7 Issue-2 International Journal of Intellectual Advancements and Research in Engineering Computations Design and analysis of bullet proof jacket Muruganantham.S1, Sabarimoorthy.S2, Sivamani.D2, Vignesh.K2, Vikneshwaran.E2 1Assistant Professor, Department of Mechanical Engineering, Nandha Engineering College, Erode-52 2UG Students, Department of Mechanical Engineering, Nandha Engineering College, Erode-52 ABSTRACT A ballistic vest or bullet-resistant vest, often called a bulletproof vest, is an item of personal armor that helps absorb the impact and reduce or stop penetration to the body from firearm-fired projectiles and shrapnel from explosions, and is worm on the torso. Now-a-days the Indian Army using bullet proof jacket that weight‟s 15-18 kg and above. Also the design of jacket is straight and curve shaped structure. The straight shape structure will passes through the vibration full bullet proof plate. So its breaks when the bullet attacking for more vibration. So we are planned to change the design of the bullet proof jacket. Index words: Design, Vibration, Structure INTRODUCTION stop before it can completely penetrate the textile matrix. Some layers may be penetrated but as the Now-a-days India using bullet proof jacket is bullet deforms, the energy is absorbed by a larger made by Kevlar. The Kevlar have high impact and larger fiber area. some vests designed for strength compare to other material using bullet bullets offers less protection against blows with the proof vest and also its an composite material. The knights of the Middle Ages. However, with the vest is straight and curve shape structure. The invention of firearms around 1500, metal body design of composite armor is a very complex task armor became ineffective. In general, the as compared to conventional single-layer metallic battlefield demands durable, reliable, light, armor, due to the exhibition of coupling among maneuverable and fast vehicles which, at the same membrane, torsion and bending strains, weak time, can provide the required level of protection transverse shear strength and discontinuity of the for the vehicle occupants. The traditional steel mechanical properties along the thickness of the armor, while providing the required level of composite laminates. This has drawn attention of protection for the on- board personnel and do it at several researchers to study the penetration a relatively low cost, contributes a prohibitively phenomenon in composite amours. large additional weight to the battle vehicles, often The first protective clothing and shields were increasing the loads beyond the levels anticipated made from animal skins. As civilizations became during from sharp implements, such as knives, more advanced, wooden shields and then metal arrows or ice picks, or from bullets manufactured shields came into use. Eventually, metal was also with hardened materials, those containing a steel used as body armor, what we now refer to as the core instead of lead. This is because the impact suit of armor associated the vehicle design. force of these objects stay concentrated in a The ballistic vest are very strong fibers to relatively small area, allow them a better “catch” and deform a bullet, mushrooming it in to likelihood the fiber layers of most bullet resistant a dish shape and spreading its force over a larger fabric‟s used in soft armor.

    ENGLISH REVISION SHEET SECOND TERM AY (2016 - 2017) Grade 10 Name: _____________________ Grade and Section: _______________ Teacher: ______________ Date: _________________________ A. Direction: Read the following passage and answer the questions that follow. Refer to the text to check your answers when appropriate. Part A: Reading Comprehension The Way of the World Bob Petersburg had been the top salesman at Midwest Motor Parts for years. He had a network of clients that spread out in every direction. His clients loved him for his affable manner and his honesty, and Bob felt that the world was his. Maybe it was Bob’s for a little while, but then the world started changing around him. It happened slowly at first with some of the other salesmen carrying pagers and using email to deal with clients. Then his sales base started eroding. Many of his old clients were retiring. Familiar faces had been replaced by young, cold faces. These new faces asked Bob for his email address. Bob said that email could never replace the intimacy of a handwritten letter. Time passed and it continued to pass by Bob. Rick Summers was Bob’s manager and he changed too. They played golf together and barbecued occasionally, but Rick's wife got sick and he retired. Rick was replaced by Mike Christmas. Rick never bothered Bob about embracing new business standards using computer, but Mike was from the new school. One of Mike's first actions as sales chief was to issue company smart phones to every salesman. When Bob did not send emails, take photos of signed purchase orders, or reply to Mike’s text messages, Mike grew impatient with him.

  • A Mix of RPG and Miniature Skirmish... « Argad ! » Is a Mix of Role-Playing and 28Mm Skirmish Rules
    April 2020 A mix of RPG and miniature skirmish... « Argad ! » is a mix of role-playing and 28mm skirmish rules. All figures represent adventurers, warriors, soldiers, or peaceful characters. Players move whole bands or small groups of characters who may have different equipments, weapons, and abilities; one character in each band represents a player. All versions and extensions of the rules are compatible and complementary. This document explains the general gaming system, same for any context or period (past, present, imaginary, or future). It is completed by reference sheets for precise contexts or historical periods, sufficient to play when basic principles of the game are understood. You do not need to read everything before playing! Place some terrain features and a few figures on the gaming table, move some figures, shoot, fight in melee, look at reference sheet summaries when needed. The game allows fast moves and daring actions and is more enjoyable if a participant acts as game master (GM as in any RPG), prepares a scenario, acts as umpire and moves some of the figures (non-player characters). Texts in blue print, or titled in blue, are optional or advanced rules which can be ignored for a simple game. Many pages in this document help to resolve situations which do not often happen in a game, you just need to know where to find them when you want them. We apologise for awkward syntax or wording. Figures & bases The rules are devised for 28mm miniatures fixed individually on round or square bases. They could work with other scales of figures.

Quality control and tests for vest like fiber and yarn tensile strength, the tensile strength of the resultant cloth Spectra is also tested for tensile strength by the manufacturer. Bulletproof vests are tested both wet and dry. This is done because the fibers used to make a vest perform differently when wet. Tests for check quality of jacket A. Ballistic testing V50 and V0 B.

In the present work, a comparison was carried out between the ballistic performance of UHMWPE composite, commercially known as Dyneema, and epoxy composite reinforced with 30 vol % natural fibers extracted from pineapple leaves (PALF) in a hard armor system. This hard armor system aims to provide additional protection to conventional level IIIA ballistic armor vests, made with Kevlar, by introducing the PALF composite plate, effectively changing the ballistic armor into level III. This level of protection allows the ballistic armor to be safely subjected to higher impact projectiles, such as 7.62 mm caliber rifle ammunition. The results indicate that a hard armor with a ceramic front followed by the PALF/epoxy composite meets the National Institute of Justice (NIJ) international standard for level III protection and performs comparably to that of the Dyneema plate, commonly used in armor vests.
