This book was released on 1975 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a comparison of five pretest predictions with the measured rigid body motion of a large penetrator normally impacting the Watching Hill Blast Range at the Defence Research Establishment, Suffield, Ralston, Alberta, Canada, at an impact velocity of about 500 ft/sec. The prediction methods used were evaluated in detail. They included the Sandia empirical penetration formulas, the spherical and cylindrical cavity expansion theories, a viscoplastic force 'law', and the AVCO differential area force 'law'. The capability of predicting peak rigid body deceleration and maximum penetration within a factor of two of measured test data was demonstrated by several of the methods.

Download or read book High speed Penetration Dynamics Engineering Models And Methods written by Gabi Ben-dor and published by World Scientific. This book was released on 2013-06-07 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important monograph is the first comprehensive compendium of engineering models used in high-speed penetration mechanics.The book consists of two parts. The first part (more than a quarter of the book's content) is in fact a handbook giving a very detailed summary of the engineering models used for the analysis of high-speed penetration of rigid projectiles into various media (concrete, metals, geological media). The second part of the book demonstrates the possibilities and efficiency of using approximate models for investigating traditional and nontraditional problems of penetration mechanics.Different chapters in the books are devoted to different classes of problems and can be read independently. Each chapter is self-contained, which includes a comprehensive literature survey of the topic, and carries a list of used notations. The bibliography includes more than 700 references.This monograph is a reliable and indispensable reference guide for anyone interested in using engineering models in high-speed penetration mechanics.

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.
Download or read book World Scientific Handbook Of Experimental Results On High Speed Penetration Into Metals Concrete And Soils written by Gabi Ben-dor and published by World Scientific. This book was released on 2016-08-18 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique compendium contains a vast systematized data of 14,000 experiments on high-velocity penetration into metals, concrete, reinforced concrete, and geological media which were published in the open literature (journal papers, reports, conference proceedings) during the last 70 years. Data presented in this edition are related to the initial and final stages of penetration and include: parameters which characterize mechanical and geometric properties of the striker and the shield; striking and residual velocities of projectile or depth of penetration; changes of mass and size of projectile; angles that determine the initial and residual position of the projectile; ballistic limit velocity; basic characteristics of plug and deformation of the shield.Unified form of data representation and common notations are used throughout the book. All information is presented in numerical form in SI units. The book also contains indices which allow a fast search of the authors' publications and related experiments. Theoreticians, design engineers and experimentalists will find this handbook a valuable reference material.

This book was released on 1987 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is the most comprehensive single undertaking to date which is directed toward an evaluation of the validity of concepts of nondestructive evaluation of the load-carrying capacity of airfield pavements. Seven nondestructive test devices tested five sections of airfield pavements at MacDill Air Force Base (AFB) which consisted of two rigid, two flexible, and one composite pavements, ranging from 20-in. portland cement concrete (PCC) to 5.5- in. asphaltic concrete. Analytical treatments of the test data included empirical correlation analyses, and layered-elastic and finite element computer analyses. Six private firms each with a different nondestructive testing (NDT) evaluation method provided evaluation results in terms of allowable aircraft loads and overlay thicknesses. The Air Force produced one set of results using its new nondestructive pavement testing method, and Waterways Experiment Station provided three sets of results. This study has shown that NDT technology exists for evaluation of airfield pavements. For the pavements at MacDill AFB, some NDT evaluation methods agreed better with the standard test-pit method than others. However, the pavements at MacDill AFB are rather nontypical, and those NDT evaluation methods that did not give good results at MacDIll may give more agreeable results on different pavements. The lack of agreement between results of the NDT evaluation methods does justify concern and may point to the need for a standard evaluation method.
