Available in PDF, EPUB and Kindle. Book excerpt: Three separate non-standard conditions of projectile impact and perforation of plates were investigated experimentally and analytically. The first concerned impingement of blunt 0.25 in. dia. hard-steel cylinders on stationary thin plates of aluminum and steel at yaw angles up to 19 deg at velocities from 115-285 m/s. Damage was produced by bulging, lateral indentation and front and side petaling. Measurements of the ballistic limit and terminal velocity were compared with predictions of a model utilizing simplifying phenomenological assumptions. Predictions underestimated the ballistic limit by up to 14% with better correlation at higher yaw angles; they were found to be in good accord with observed final speeds. The second topic involved the effect of striker tumbling on the impact response of thin and moderately thick stationary targets of aluminum, steel and polycarbonate. The 1/2 in dia. blunt projectiles impinged the plates at longitudinal speeds from 250-700 m/s and rotational speeds up to 3600 rad/s. Perforation and post-perforation measurements, including final velocities, oblique angles and crater sizes compared well with predictions of both an analytical and a numerical model.

This book was released on 1966 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook presents a general survey of the principal factors affecting the flight of projectiles, and describes the methods commonly used for predicting and influencing the flight performance. The coefficients which characterize the aerodynamic forces and moments of a moving body are identified, methods for determining the coefficients applicable to a projectile having a given shape and center of gravity location are described, and the coefficients of a number of projectiles and projectile shapes are given. The use of aerodynamic coefficients in predicting stability, range and accuracy is described. The effects of variations in projectile shape and center of gravity location on range, accuracy and lethality are discussed. Some material on prototype testing and the effects of round-to-round variations in production lots is presented.

Available in PDF, EPUB and Kindle. Book excerpt: Presents high-level research on various caliber guns, cannon, mortars, drones, warheads, shells, bullets, drills and other launchers and penetrants, as well as their impact effects on natural and designed materials, including large-scale targets and body armors Provides new modeling and test data on projectile design and guidance, propellants, charges and explosives for military, aerospace and civil engineering applicationsOver 250 presentations in two printed volumes, plus searchable CD This book makes available original ballistics technology from around the world on a wide variety of weapons and their effects, including the design and trajectory/stability control of dozens of projectiles ranging from shells to missiles. The book's authors discuss the efficacy and development of propellants, munitions, and igniters and offer new approaches for modeling and testing. Also investigated in Volume 1 are shielding and protection strategies for individual persons and other targets. Volume 2 offers research on the mechanical behavior of multiple types of explosives, as well as impact and penetration data from projectile effects on surfaces ranging from natural phenomena such as water and soils to metallic plating and material-engineered armors. Papers in these volumes were presented at a conference organized by the National Defense Industrial Association (NDIA) with the International Ballistics Society.

Download or read book Terminal Ballistics written by Zvi Rosenberg and published by Springer Nature. This book was released on 2020-06-01 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively discusses essential aspects of terminal ballistics, combining experimental data, numerical simulations and analytical modeling. This new, 3rd edition reflects a number of recent advances in materials science, such as the use of polyurea layers on metallic plates in order to improve their ballistics. In addition, more data and analyses are now available on dwell and interface defeat in ceramic tiles coated with polymers, and are presented here. Lastly, the new edition includes new results, numerical and empirical, concerning the DIF issue in brittle solids, as well as the “upturn” phenomenon in the stress–strain curves of ductile solids.The author also added a new analysis of concrete penetration experiments which accounts for the scaling issue in this field. This is a new,and important, addition which we are happy to announce. They also added some new insights into the interaction of EEP’s and FSP projectiles with metallic plates. Throughout the book, the authors demonstrate the advantages of the simulation approach in terms of understanding the basic physics behind the phenomena investigated, making it a must-read for all professionals who need to understand terminal ballistics.

This book was released on 1976 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cylindrical rod on rod impact model is developed that allows for linear elastic strains in the projectile and linear elastic-plastic strains in the target plug. Application is made to the plate impact problem. Normal incidence impact of two circular cylinders is considered. One-dimensional stress waves load the projectile and the plug in compression and tension. Stress wave interactions are tracked in the projectile and in the plug. Momentum balance is used to solve for resultant stresses and particle velocities. Optimum conditions are determined for the initial impact that allow the plug to be accelerated uniformly to the initial projectile velocity. Optimum plug length/projectile length ratio is found to decrease with increasing projectile initial velocity. Separation of the projectile and plug is predicted and separation times are determined.
