A technique for conducting instrumented Charpy impact tests using a Hopkinson bar is presented. Data for three grades of beryllium covering a range in impact velocities from 20 to 200 in/sec (.5 to 5 mm/s) are obtained in the form of load-deflection curves from which maximum load, maximum deflection, and total energy are obtained. Results show good agreement with data on identical materials obtained from an instrumented impact test at 54 in/sec (1.37 m/s) and from a standard Charpy impact machine at 135 in/sec (3.43 m/s). The advantages and limitations of the Hopkinson bar apparatus are discussed.

Instrumented Impact Testing For Evaluating End Use Performance written by DR. Ireland and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1981 with Component testing categories.

Several applications of the instrumented impact test for evaluations of polymers and fiber reinforced polymers are discussed. These include simple flex bar, falling dart, and end-use component tests. Instrumented impact testing provides a complete record of the load applied to the specimen during the entire impact event. Distinct characteristics of the load record indicate the deformation and fracture process in the specimen. Subsequent analysis permits detailed study of the various fracture modes. Total absorbed energy is simply segmented into that required for initiating failure and that for propagating the fracture. Results of the laboratory impact test can then be evaluated with respect to the specific properties of interest for the product end-use.

The authors systematically describe the general principles of Kolsky bars, or split Hopkinson bars, which are widely used for obtaining dynamic material properties. Modifications are introduced for obtaining reliable data. Specific experiment design guidelines are provided to subject the specimen to desired testing conditions. Detailed Kolsky-bar examples are given for different classes of materials (brittle, ductile, soft, etc) and for different loading conditions (tension, torsion, triaxial, high/low temperatures, intermediate strain rate, etc). The Kolsky bars used for dynamic structural characterization are briefly introduced. A collection of dynamic properties of various materials under various testing conditions is included which may serve as a reference database. This book assists both beginners and experienced professionals in characterizing high-rate material response with high quality and consistency. Readers who may benefit from this work include university students, instructors, R & D professionals, and scholars/engineers in solid mechanics, aerospace, civil and mechanical engineering, as well as materials science and engineering.

Updated throughout for the new edition, Armour: Materials, Theory, and Design covers extant and emergent protection technologies driving advances in armour systems. Covering materials, theory and design, the book has applications in vehicle, ship, personnel and building use. Introducing a wide range of armour technologies, the book is a key guide to the technology used to protect against both blasts and ballistic attacks. Chapters cover bullets, blasts, jets and fragments, as well as penetration mechanics. The new edition builds on the previous one, discussing ceramics and metallic materials as well as woven fabrics and composite laminates. Detailing modern technology advancements, the second edition has also been expanded to include improved explanations on shock mechanisms and includes significantly more figures and diagrams. An essential guide to armour technology, this book outlines key ways to implement protective strategies applicable for many types of conflict.

With organizations and individuals increasingly dependent on the Web, the need for competent, well-trained Web developers and maintainers is growing. Helping readers master Web development, Dynamic Web Programming and HTML5 covers specific Web programming languages, APIs, and coding techniques and provides an in-depth understanding of the underlying concepts, theory, and principles. The author leads readers through page structuring, page layout/styling, user input processing, dynamic user interfaces, database-driven websites, and mobile website development. After an overview of the Web and Internet, the book focuses on the new HTML5 and its associated open Web platform standards. It covers the HTML5 markup language and DOM, new elements for structuring Web documents and forms, CSS3, and important JavaScript APIs associated with HTML5. Moving on to dynamic page generation and server-side programming with PHP, the text discusses page templates, form processing, session control, user login, database access, and server-side HTTP requests. It also explores more advanced topics such as XML and PHP/MySQL. Suitable for a one- or two-semester course at the advanced undergraduate or beginning graduate level, this comprehensive and up-to-date guide helps readers learn modern Web technologies and their practical applications. Numerous examples illustrate how the programming techniques and other elements work together to achieve practical goals. Online Resource Encouraging hands-on practice, the book’s companion website at http://dwp.sofpower.com helps readers gain experience with the technologies and techniques involved in building good sites.
