The role of various parameters such as angle of impact, velocity of impact, angular velocity of bullet and mass of the bullet have been investigated numerically using finite element method. To start with, a configuration from literature has been taken and numerically investigated to establish the robust simulation technique based on explicit dynamics. The demonstrated estimated simulation result agrees to the reported experimental result adequately. Subsequently, various configurations of bullets such as ak47 $7.62times 39$ bullet, $7.62times 25$ bullet and hollow point bullet have been taken for investigation. The influence of angle of impact has been examined by changing the angle of impact (0°-60°) with constant linear and angular speed. Subsequently, the linear and angular velocities, and density of the bullets have been varied with respect to angle on incidence and the corresponding results have been demonstrated to understand the most optimal performance of the bullet and bullet parameters. Moreover, the estimated penetration depths and analytical validation of kinetic energy for all configurations have been presented in the paper in detail.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123073073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Embedded passive technology enables classical passive surface mount components such as resistors, capacitors & inductors to be integrated inside the layers of the primary interconnect substrate. The main drivers for the embedded resistor technology are size reduction, increased functionality, improved high frequency performance and also increased reliability due to elimination of solder joints. These advantages led to Design and Development of Compact DTRMC card. The board controls Transmit/Receive Modules (T/R Module), consisting of single Lattice Field Programmable Gate Array (FPGA) which controls 2-Transmit/Receive modules simultaneously. The overall objective of this controller is to receive command and control data from Higher Level Controller, configures both the T/R Module as per commands and also monitors the Status/Health of both the Modules. The Communication link is High speed 10-Mbps full duplex Low Voltage Differential Signalling (LVDS) serial link. Compact DTRMC PCB Layout design is done optimally using controlled impedance techniques. Layout is done to take care of crosstalk, reflections and Electromagnetic Interference (EMI) issues. The Multilayer PCB is designed to ensure Electromagnetic Compatibility (EMC) so as to meet the high-speed performance requirements of control signals required for both the T/R modules. The Compact DTRMC card is an 8- layer PCB with Microvia & 28nos of embedded resistors with a csBGA package of 0.5 mm pitch. Via-on-pad technique is adapted for routing the signals near BGA. The Board is designed, fabricated, tested and found to meet all the requirements.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128627626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
