Book Description
The principal mission of the Penetration Mechanics Branch (PMB) of the Terminal Ballistics Division (TBD) of the Ballistic Research Laboratory (BRL). Aberdeen Proving Ground, MD, is research and development leading to improvements in the terminal ballistic performance of kinetic energy (KE) long rod penetrators. This is done by using computer modeling and by experimental tests. In terms of the number of shots fired, the experimental testing is predominantly done at reduced scale using laboratory guns with bore diameters of 20 to 30 mm. The reduced scale penetrators are of simplified geometry compared with their full-scale counterparts. The penetrator is usually a monolithic right-circular-cylinder metal rod with a hemispheric nose made from either tungsten alloy (WA) or depleted uranium (DU). Terminal ballistics is that part of the science of ballistics that relates to the interaction between a projectile (penetrator) and a target. In general, the projectile is the package which flies through the air. The penetrator is the part of the projectile which digs into the target, inflicting damage to the target. The primary measure of the effectiveness of a penetrator attacking a specific target is its ballistic limit velocity. The ballistic limit velocity is the impact speed required to just get through the target placed at the specified angle of obliquity.

Book Description
This monograph covers all important issues of terminal ballistics in a comprehensive way combining experimental data, numerical simulations and analytical modeling. It uses a unique approach to numerical simulations as sensitivity measure for the major physical parameters. In the first chapter, the book includes necessary details about the experimental equipment which are used for ballistic tests. The second chapter covers essential features of the codes which are used in recent years all over the world, the Euler vs. Lagrange schemes, meshing techniques etc. The third chapter, devoted to the penetration mechanics of rigid rods, brings the update of modeling in this field. The fourth chapter deals with plate perforation and the fifth chapter deals with the penetration of shaped charge jets and eroding long rods. The last chapter includes several techniques for the disruption and defeating of the main threats in armor design. Throughout the book the authors demonstrate the advantages of the simulation approach in understanding the basis physics behind the investigated phenomena.

Book Description
Ballistic Materials and Penetration Mechanics deals with ballistically protective materials and penetration mechanics. The book discusses historical and practical considerations of ballistic protection, including metallic armor, as well as ballistic testing methodology, the ability of a protective material to stop or slow down a particular projectile, and the theoretical aspects of penetration mechanics. It also highlights the importance of stress wave analysis in the penetration and spalling phenomena. Organized into 12 chapters, this volume begins with an overview of the history of the armor and the modern helmet. It proceeds with a discussion of variations in ballistic test methods, errors in test methods, and the importance of the hardness and geometry of both the target and the projectile. The next chapters focus on the importance of fibrous armor, materials that are visually transparent and resistant to penetration by high-energy projectiles and fragments, and transparent armor and ceramic composite armor. The reader is also introduced to materials used in the design of metallic armor, the role of stress waves in the penetration problem, and the use of computer simulation to analyze ballistic impact experiments. The book looks at numerical techniques for modeling hypervelocity impact and concludes with a chapter on the penetration mechanics of textile structures. This book is a valuable resource for scientists working at government, industrial, and university laboratories, as well as law enforcement officers and others who want information on materials that provide the best protection against damage from impacts, explosions, and bullets.

Book Description
Academic researchers who are working on the development of composite materials for ballistic protection need a deeper understanding on the theory of material behavior during ballistic impact. Those working in industry also need to select proper composite constituents, to achieve their desired characteristics to make functional products. Composite Solutions for Ballistics covers the different aspects of ballistic protection, its different levels and the materials and structures used for this purpose. The emphasis in the book is on the application and use of composite materials for ballistic protection. The chapters provide detailed information on the various types of impact events and the complexity of materials to respond to those events. The characteristics of ballistic composites and modelling and simulation results will enable the reader to better understand impact mechanisms according to the theory of dynamic material behavior. A complete description of testing conditions is also given that includes sensors and high-speed devices to monitor ballistic events. The book includes detailed approaches and schemes that can be implemented in academic research into solutions for ballistic protection in both theoretical and experimental fields, to find solutions for existing and next generation threats. The book will be an essential reference resource for materials scientists and engineers, and academic and industrial researchers working in composite materials and textiles for ballistic protection, as well as postgraduate students on materials science, textiles and mechanical engineering courses. - Discusses the fundamentals of impact response mechanisms and related solutions covering advantages and disadvantages for both existing and next generation applications - Includes various methods for evaluation of ballistic constituents according to economic and environmental criteria, types of green ballistics are considered to enhance sustainable production of applications as well as hybrid composites from natural wastes - Discusses selection methodologies for ballistic applications and detailed information on the use of textiles for reinforcement fabrication

Book Description
This report presents the results of an experimental program to examine the performance of a reduced-mass concept penetrator impacting semi- infinite rolled homogeneous armor (RHA) at normal incidence. The reduced-mass penetrator ueed in this program is a solid tungsten alloy rod with eight holes drilled parallel to its axis, equally spaced on a circle, with axes parallel to the rod axis. Its performance was contrasted with baseline data for length-to- dameter ratios (L/D) 4 and 5 solid tungsten alloy penetrators. Striking velocity was nominally 1.6 km/s. A determined effort to reduce the scatter in the data by analysis of collateral data from the U.S. Army Research Laboratory (ARL) and literature sources suggested only a rather weak influence of L/D on penetration even at L/Ds approaching 1 and provided a tentative relationship to remove the influence of target lateral edge effects. It tightened up the holed-out rod data enough to be able to conclude with a moderate degree of certainty that there was no improvement in penetration as suggested by a simplistic density law model. A companion work by Kimsey of ARL examines the performance of this novel penetrator concept computationally, using the Eulerian code CTH. His work explains the possible causes of reduced performance suggested by analysis by Zook and Frank of ARL, though with some relative improvement in performance at higher velocities.
