This book was released on 1974 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of annealing temperature on the high strain rate behavior of OFHC copper and a tellurium doped free machining copper is investigated. The annealing temperatures studied include temperatures above and below as well as the recrystalization temperature. The torsional split Hopkinson bar is utilized to achieve shear strain rates up to 2,000/s with a rise time of ten microseconds. The resulting stress-strain curves are compared with those obtained at a strain rate of .0001/s. Specimens of OFHC copper are subjected to incremental strain rate tests so that the change in flow stress corresponding to an increase in strain rate can be evaluated for each specimen. It is concluded that the strain rate sensitivity is positive in nature for each temperature and that its magnitude depends on the annealing temperature. (Author).

This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUTAM Symposium on Macro- and Micro-Mechanics of High Velocity Deformation and Fracture (MMMHVDF) (August 12 - 15, 1985) was held at Science Council of Japan, under the sponsor ship of IUTAM, Science Council of Japan, Japan Society for the Promotion of Science, The Commemorative Association for the Japan World Exposition (1970), and The Japan Society for Aeronautical and Space Sciences. The proposal of the symposium was accepted by the General Assembly of IUTAM, and the scientists mentioned below were appointed by the Bureau of IUTAM to serve as member of the Scientific Committee. The main object of the Symposium was to make a general survey of recent developments in the re search of high velocity solid mechanics and to explore further new ideas for dealing with unsettled problems, of fundamental nature as well as of practical importance. The subjects covered theoretical, experimental, and numerical fields in macro- and micro-mechanics associated with high velocity de formatio~ and fracture in soldis, covering metals, ceramics, polymers, and composites.

This book was released on 2013-03-07 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army Materials and Mechanics Research Center in coopera tion with the Materials Science Group of the Department of Chemical Engineering and Materials Science of Syracuse University has been conducting the Annual Sagamore Army Materials Research Conference since 1954. The specific purpose of these conferences has been to bring together 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. The proceedings of this conference, entitled MATERIAL BEHAVIOR UNDER HIGH STRESS AND ULTRAHIGH LOADING RATES, will be published in two parts. The topics covered in the present volume include dynamic plasticity, adiabatic shear/localized deformation, and dynamic fracture mechanics. Papers dealing with ordnance applica tions, projectile launch environment, and recent work-in-progress will appear as an AMMRC Technical Report and will have more limited distribution in accordance with recent Army guidelines. The Conference Chairmen are particularly grateful to the members of the Program Committee. We wish also to acknowledge the assistance of Mr. Charles Polley of the Army Materials and Mechanics Research Center, Mr. Robert Sell, Ms. Helen Brown DeMascio, and Ms. Mary Ann Holmquist of Syracuse University throughout the con ference planning stages and the publication of the text. The continued active interest in and support of these confer ences by Dr. E. Wright and Col. George Sibert, Direct and Deputy Director/Commander, respectively, of the Army Materials and Mechan ics Research Center, is appreciated.

Download or read book The Influence of Strain Rate History and Temperature on the Shear Strength of Copper Titanium and Mild Steel written by A. M. Eleiche and published by . This book was released on 1976 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments have been carried out to determine the strain-rate sensitivity of the shear flow stress of OFHC copper, commercially-pure titanium and mild steel over the temperature range -150 to 400 C. All the tests were performed on thin-walled tubular specimens of short gauge length, mounted in a torsional split Hopkinson-bar apparatus adapted to permit quasi-static straining as well as dynamic straining. For each material, the constant-rate behaviour was first measured at nominal strain rates of ten to the minus 3rd power and ten to the 3rd power s to the minus 1st power, for six different temperatures. Tests were then carried out in which the strain rate was suddenly increased from ten to the minus 3rd power to ten to the 3rd power s to the minus 1st power at various values of plastic strain. Comparison of the results obtained in the two series of tests shows that the response of all three materials depends on the strain-rate history, so that a 'mechanical equation of state', relating stress to strain, strain rate and temperature is not valid; however, the influence of strain-rate history is less marked for titanium than for copper or mild steel. The results are discussed in terms of plastic flow mechanisms involved, thermal activation, changes in microstructure, strain ageing and dynamic recovery. Possible forms of macroscopic constitutive relation are also discussed.

Download or read book Nano and Cell Mechanics written by Horacio D. Espinosa and published by John Wiley & Sons. This book was released on 2012-12-12 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in nano and cell mechanics has received much attention from the scientific community as a result of society needs and government initiatives to accelerate developments in materials, manufacturing, electronics, medicine and healthcare, energy, and the environment. Engineers and scientists are currently engaging in increasingly complex scientific problems that require interdisciplinary approaches. In this regard, studies in this field draw from fundamentals in atomistic scale phenomena, biology, statistical and continuum mechanics, and multiscale modeling and experimentation. As a result, contributions in these areas are spread over a large number of specialized journals, which prompted the Editors to assemble this book. Nano and Cell Mechanics: Fundamentals and Frontiers brings together many of the new developments in the field for the first time, and covers fundamentals and frontiers in mechanics to accelerate developments in nano- and bio-technologies. Key features: • Provides an overview of recent advances in nano and cell mechanics. • Covers experimental, analytical, and computational tools used to investigate biological and nanoscale phenomena. • Covers fundamentals and frontiers in mechanics to accelerate developments in nano- and bio-technologies. • Presents multiscale-multiphysics modeling and experimentation techniques. • Examines applications in materials, manufacturing, electronics, medicine and healthcare. Nano and Cell Mechanics: Fundamentals and Frontiers is written by internationally recognized experts in theoretical and applied mechanics, applied physics, chemistry, and biology. It is an invaluable reference for graduate students of nano- and bio-technologies, researchers in academia and industry who are working in nano and cell mechanics, and practitioners who are interested in learning about the latest analysis tools. The book can also serve as a text for graduate courses in theoretical and applied mechanics, mechanical engineering, materials science, and applied physics.
