Book excerpt: This compendium of mathematical techniques for the modeling and simulation of high-velocity impacts presents the various analytical and experimental aspects of impact dynamics and describes the responses of a variety of materials and structures under impact. Coverage is extended beyond that of the author's Impact Dynamics and deals with new topics in impacts involving inert materials, including the dynamic response to energetic and inert materials.

Book excerpt: High energy impact phenomena have been investigated by engineers of various backgrounds and disciplines. Structures often need to be designed against impact or potential attack and on the other hand the removal of decommissioned structures may be achieved by shaped charge impact, alternatively known as explosive cutting. The topic of ballistic impact is wide-ranging and encompasses various levels of kinetic energy input as well as a multitude of projectile-target materials and geometries. It has thus become the object of many experimental and analytical investigations resulting in numerous sparsely-spread articles in periodicals and conference proceedings as well as monographs narrowly focusing on specific types and ranges of impact scenarios. This volume describes a broad spectrum of analytical and experimental work in this area, thus providing considerable insight into the complexity and diversity of impact phenomena. By addressing a significant number of important issues it combines, rather uniquely, subject breadth and density with in-depth study of impact events of great engineering interest.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding multi-projectile impact events is important for a wide range of military and aerospace applications. However, experimental studies in this field remain technologically challenging. In this thesis, simulations of two 20 mm caliber projectiles impacting a steel target above the ballistic limit were performed. Peridynamics, a non-local, particle-based computational method, was used to simulate the impacts. The spacing between the two impacts on target was varied to study the effects on projectile residual velocity, projectile deformation, and fragmentation. To optimize the Peridynamic parameters, the simulation results from a single impact were compared to experimental data available in the literature. Methods to track and quantify the kinetic energy, direction, mass, and velocity of individual fragments, including the projectile post impact, were developed. The size of the fragmentation field, the variation of individual fragments, and the residual velocity of the projectile post impact were studied. From the double impact study, we find increased projectile residual velocity, reduced projectile deformation, and greater variation in the fragmentation field with impacts from a second projectile compared to a single impact. It is observed that the increases in projectile residual velocity and reduction in projectile deformation diminish to near first impact levels as the projectile spacing is increased. The projectile is also found to ricochet in closer spacings causing large velocity components normal to the projectile's flight path and reduced damage to the plate. The overall size of the fragmentation field of double impact cases is found to be similar in size to single impacts, however, the number of fragments produced from the impacts are different. In cases where the second projectile impacted closer to the initial impact, only one fragment was formed, while cases with spacing 1.25 calibers and greater produced more fragments than the initial impact. This thesis proved to be successful in employing Peridynamic theory to study complex impact and fragmentation related problems.

This book was released on 1966 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ballistic parameters were determined analytically and experimentally for the perforation of aluminum alloy and titanium alloy plates by normal impact of steel cylinders. Analytical predictions of the perforation parameters were prepared on the basis of theoretical models of the perforation process. Experimental determination of the critical perforation and residual velocities discriminated among the various models and further experimentation verified the analytical description of the perforation process. One model of perforation was found which adequately describes the ballistic parameters for the normal impact of steel cylinders into aluminum alloy and titanium alloy plates for impact velocities up to 5000ft/sec and plate thicknesses up to 0.25 inches.

This book was released on 2006-02-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-speed impact dynamics is of interest in the fundamental sciences, e.g., astrophysics and space sciences, and has a number of important applications in military technologies, homeland security and engineering. When compared with experiments or numerical simulations, analytical approaches in impact mechanics only seldom yield useful results. However, when successful, analytical approaches allow us to determine general laws that are not only important in themselves but also serve as benchmarks for subsequent numerical simulations and experiments. The main goal of this monograph is to demonstrate the potential and effectiveness of analytical methods in applied high-speed penetration mechanics for two classes of problem. The first class of problem is shape optimization of impactors penetrating into ductile, concrete and some composite media. The second class of problem comprises investigation of ballistic properties and optimization of multi-layered shields, including spaced and two-component ceramic shields. Despite the massive use of mathematical techniques, the obtained results have a clear engineering meaning and are presented in an easy-to-use form. One of the chapters is devoted solely to some common approximate models, and this is the first time that a comprehensive description of the localized impactor/medium interaction approach is given. In the monograph the authors present systematically their theoretical results in the field of high-speed impact dynamics obtained during the last decade which only partially appeared in scientific journals and conferences proceedings.
Download or read book Ballistic Impact Between a Blunt Elastic Projectile and an Elastic Plastic Plate written by Kenneth C. Leone and published by . 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.
