Download or read book Empirical Analysis of Projectile Penetration in Rock written by Robert S. Bernard and published by . This book was released on 1977 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The data base consists of normal impact and penetration data for rock (11 tests) and for concrete (12 tests, used as a baseline). The test projectiles had ogive noses, diameters between 76 and 203 mm, masses between 5.9 and 613 kg, and impact velocities from 251 to 809 m/s. The rock penetration equation is given in dimensional form and also in nomogram form. Calculated results are compared with badly scattered bomb penetration data for granite and sandstone. The equation gives about the same result as a least-squares linear fit to the data.
Download or read book Non Normal Projectile Penetration in Soil and Rock User s Guide for Computer Code PENC02D written by Daniel C. Creighton and published by . This book was released on 1982 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program called PENCO2D has been developed to analyze the non-normal impact and penetration of any rigid axisymmetric projectile into soil or rock. Horizontal target layering is allowed with accounts made for free-surface, interface, and wake separation-reattachment effects. Expressions for the compressive normal stress presented in U.S. Army Engineer Waterways Experiment Station Technical Report SL-79-15 are summed over the projectile surface, and the equations of motion are integrated step-by-step using a two-dimensional Newtonian integration scheme. Variables and format of PENCO2D's input file, as well as output options, are given. To demonstrate use of PENCO2D, three sample problems are discussed, with setup and output shown. A utility program called MOMENT, which calculates projectile weight, center-of-gravity location, and mass moments of inertia, its presented along with two example calculations. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Rapid Penetration into Granular Media: Visualizing the Fundamental Physics of Rapid Penetration introduces readers to the variety of methods developed to visualize, observe, and model the rapid penetration of natural and man-made projectiles into earth materials while providing seasoned practitioners with a standard reference that showcases the topic's most recent developments in research and application. There has been a flurry of recently funded research both in the U.S. and Europe on studying the behavior of projectiles in granular media. This book compiles the findings of recent research on the subject and outlines the fundamental physics of rapid earth penetration, and assembles a comprehensive collection of experimental and numerical techniques to study the problem. - Presents a comprehensive interdisciplinary review of the latest research developments in the response of granular media to impact and impulsive loading - Combines the experience of prominent researchers from different disciplines focusing on the challenges presented by impact loading of granular media - Introduces recently developed methods for visualizing the fundamental physics of rapid penetration into granular media

Download or read book Analysis of Projectile Penetration Into Concrete and Rock Targets written by Behzad Rohani and published by . This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents several examples of penetration calculations for rigid projectiles impacting concrete and rock targets. The calculations were performed with a computer code which is based on the theory of dynamic cavity expansion in an elastic-plastic compressible continuum. The results of the penetration calculations compare favorably with available data from field experiments and with the results from published finite-difference code calculations. The influence of various target material parameters, different initial impact velocities, and projectile size and shape changes on concrete and rock penetration was also assessed. The accuracy and range of application of the penetration model, however, must still be determined experimentally under more diverse impact conditions.
Download or read book Projectile Impact written by S. Syngellakis and published by WIT Press. This book was released on 2014-03-04 with total page 245 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Engineering Models In High speed Penetration Mechanics And Their Applications In 2 Volumes written by Gabi Ben-dor and published by World Scientific. This book was released on 2018-12-28 with total page 1116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume, 1100 pages, 38 chapters book is a significantly expanded, revised and updated version of the monograph by the authors published in 2013 (Ben-Dor, G, Dubinsky, A, Elperin, T, 'High Speed Penetration Dynamics: Engineering Models and Methods,' Singapore: World Scientific Publishing Company). The contents increased by 60%, the number of titles in bibliography doubled and reached 1600; and the scope covers a range of new topics related to hypervelocity penetration, along with high-speed impact.Presented material is structured into two parts. The first part includes description and analysis of practically all known engineering models for calculating high-speed penetration of projectiles into concrete, metals, geological shields, adobe, and gelatine.The second part focuses on the use of approximate models for solving conventional and non-standard problems of penetration mechanics including prediction and optimization of protective properties of monolithic and multi-layered shields against high-speed projectiles and space debris; shape optimization of high-speed projectiles penetrating into various media; modelling of penetration and optimal control of penetrators equipped with jet thrusters; and investigation of the efficiency and optimization of segmented projectiles. The book includes comprehensive overviews on basic classes of problems in high-speed penetration mechanics.This is a indispensable reference guide for scientists, engineers, and students specializing in the field of high-speed and hypervelocity penetration mechanics.
