Book Synopsis Effect of Low-velocity Or Ballistic Impact Damage on the Strength of Thin Composite and Aluminum Shear Panels by : G. L. Farley
Download or read book Effect of Low-velocity Or Ballistic Impact Damage on the Strength of Thin Composite and Aluminum Shear Panels written by G. L. Farley and published by . This book was released on 1985 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impact tests were conducted on shear panels fabricated from 6061-T6 aluminum and from woven-fabric prepreg of DuPont Kevlar fiber/epoxy resin and graphite fiber/epoxy resin. The shear panels consisted of three different composite laminates and one aluminum material configuration. Three panel aspect ratios were evaluated for each material configuration. Composite panels were impacted with a 1.27-cm diameter aluminum sphere at low velocities of 46 m/sec and 67 m/sec. Ballistic impact conditions consisted of a tumbled 0.50-caliber projectile impacting loaded composite and aluminum shear panels. The results of these tests indicate that ballistic threshold load (the lowest load which will result in immediate failure upon penetration by the projectile) varied between 0.44 and 0.61 of the average failure load of undamaged panels. The residual strengths of the panels after ballistic impact varied between 0.55 and 0.75 of the average failure strength of the undamaged panels. The residual strengths of the panels after ballistic impact varied between 0.55 and 0.75 of the average failure strength of the undamaged panels. The low-velocity impacts at 67 m/sec caused a 15- to 20-percent reduction in strength, whereas the impacts at 46 m/sec resulted in negligible strength loss. Good agreement was obtained between the experimental failure strengths and the predicted strength with the point stress failure criterion. Keywords include: Composite materials; Shear panels; Damage tolerance; Low-velocity impact; Ballistic damage; Postbuckling; Helicopter; and Fuselage.

This book was released on 2012-12-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army Materials and Mechanics Research Center of Water town, Massachusetts in cooperation with the Materials Science Group of the Department of Chemical Engineering and Materials Science of Syracuse University has conducted the Sagamore Army Materials Research Conference since 1954. The main purpose of these conferences has been to gather together over 150 scientists and engineers from academic institutions, industry and government who are uniquely qualified to explore in depth a subject of importance to the Department of Defense, the Army and the scientific community. This volume, RISK AND FAILURE ANALYSIS FOR IMPROVED PERFORMANCE AND RELIABILITY, addresses the areas of Techniques of Failure Analysis, Risk and Failure Analysis for Design Against Fracture, Risk and Failure Analysis for Design Against Fatigue, Elevated Temperature Effects, Environmental Effects, Systems Approach to Production Reliability Integration and Outlook - Emerging Needs and Techniques. We wish to acknowledge the dedicated assistance of Joseph M. Bernier of the Army Materials and Mechanics Research Center and Helen Brown DeMascio of Syracuse University throughout the stages of the conference planning and finally the publication of this book is deeply appreciated.
Book Synopsis Mechanics of Composite Materials by : Zvi Hashin
Download or read book Mechanics of Composite Materials written by Zvi Hashin and published by Elsevier. This book was released on 2013-10-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanics of Composite Materials: Recent Advances covers the proceedings of the International Union of Theoretical and Applied Mechanics (IUTAM) Symposium on Mechanics of Composite Materials. The book reviews papers that emphasize fundamental mechanics, developments, and unresolved problems of the field. The text covers topics such as mechanical properties of composite materials; influence of microstructure on the thermoplastics and transport properties of particulate and short-fiber composites; and further applications of the systematic theory of materials with disordered constitution. The selection also explains the curved thermal crack growth in the interface of a unidirectional carbon-aluminum composite and energy release rates of various microcracks in short-fiber composites. The book will be of great interest to researchers and professionals whose line of work requires the understanding of the mechanics of composite materials.
