Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a discussion of the strain rate history effects that occur during the deformation of body-centered-cubic (BCC) metals. It is divided into two parts: a brief review of previous work, which also includes some new data, followed by an analysis of material behavior based on previous and new results. The review discusses early experiments on steels and other BCC metals in which interrupted tests were performed. These tests consist of loading initially at one strain rate, unloading, and reloading at a second strain rate, either higher or lower than the first. Early experiments of this type had revealed a substantial difference in response between BCC and face-centered-cubic (FCC) metals. The review also includes results of incremental strain rate tests with large jumps in strain rate, augmented by a series of experiments designed to study strain rate history effects in steel. The latter consist of incremental tests performed on specimens of an AISI 1020 hot-rolled steel over the temperature range 83 K
Download or read book Mechanical Behaviour of Engineering Materials written by Y.M. Haddad and published by Springer. This book was released on 2012-11-19 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph consists of two volumes and provides a unified, comprehensive presentation of the important topics pertaining to the understanding and determination of the mechanical behaviour of engineering materials under different regimes of loading. The large subject area is separated into eighteen chapters and four appendices, all self-contained, which give a complete picture and allow a thorough understanding of the current status and future direction of individual topics. Volume I contains eight chapters and three appendices, and concerns itself with the basic concepts pertaining to the entire monograph, together with the response behaviour of engineering materials under static and quasi-static loading. Thus, Volume I is dedicated to the introduction, the basic concepts and principles of the mechanical response of engineering materials, together with the relevant analysis of elastic, elastic-plastic, and viscoelastic behaviour. Volume II consists of ten chapters and one appendix, and concerns itself with the mechanical behaviour of various classes of materials under dynamic loading, together with the effects of local and microstructural phenomena on the response behaviour of the material. Volume II also contains selected topics concerning intelligent material systems, and pattern recognition and classification methodology for the characterization of material response states. The monograph contains a large number of illustrations, numerical examples and solved problems. The majority of chapters also contain a large number of review problems to challenge the reader. The monograph can be used as a textbook in science and engineering, for third and fourth undergraduate levels, as well as for the graduate levels. It is also a definitive reference work for scientists and engineers involved in the production, processing and applications of engineering materials, as well as for other professionals who are involved in the engineering design process.
Download or read book Metallurgical Effects at High Strain Rates written by R. Rohde and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conference on Metallurgical Effects at High Strain Rates was held at Albuquerque, New Mexico, February 5 through 8, 1973, under joint sponsorship of Sandia Laboratories and the Physical Metallurgy Committee of The Metallurgical Society of AIME. This book presents the written proceedings of the meeting. The purpose of the conference was to gather scientists from diverse disciplines and stimulate interdisciplinary discussions on key areas of materials response at high strain rates. In this spirit, it was similar to one of the first highly successful con ferences on this subject held in 1960, in Estes Park, Colorado, on The Response of Metals to High Velocity Deformation. The 1973 conference was able to demonstrate rather directly the increased understanding of high strain rate effects in metals that has evolved over a period of roughly 12 years. In keeping with the interdisciplinary nature of the meeting, the first day was devoted to a tutorial session of invited papers to provide attendees of diverse backgrounds with a common basis of understanding. Sessions were then held with themes centered around key areas of the high strain rate behavior of metals.
Download or read book Strain Rate and History Effects on the Deformation of Metals written by K. C. Valanis and published by . This book was released on 1976 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work falls into two main categories: (i) The Endochronic Constitutive Theory and (ii) The Endochronic Theory of Fracture. Both these theories constitute significant innovations over what was the state of the art prior to their development. They are based on the concept of intrinsic time put forward by Valanis. Of far greater significance, however, is the fact that both theories have been demonstrate to be valid mathematical representations of material behavior as observed in the laboratory, and they unify, possibly for the first time constitutive and fracture behavior of metals. On the conceptual level they establish two conclusions: (a) The yield surface is not necessary for the description of plastic behavior and (b) History, yet rate independent behavior, can be formulated within the framework of the theory of thermodynamics of internal variables as formulated and developed by the principal investigator.

Download or read book Shock Waves and High Strain Rate Phenomena in Metals written by Mare Meyers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1084 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific understanding of high-velocity deformation has advanced substantially during the past decade. On the one hand, the framework for a theory explaining the metallurgical effects of shock waves is beginning to take shape; on the other hand, the technological applications of high strain-rate processes have found their way into industries in countries around the world. Ex plosive cladding, welding, forming, compaction and consolidation, cutting, and hardening, in addition to high energy-rate deformation processes using other energy sources, are some of the topics of contemporary technological importance. Metallurgical effects are of the utmost importance in both the scientific understanding of the phenomena involved, and in the successful development and utilization of the associated applications. The international conference upon which this book is based had as its major objectives the acceleration of progress in the field of high-strain rate deformation and fabrication, including applications, by providing a forum for the exchange of state-of-the art information on the metallurgical effects of high strain-rate deformation and fabrication; and the organization of this informa tion into a timely and coherent body of knowledge focused around significant areas and applications. This volume is a manifestation of these objectives. In addition, the contents of this book were organized to provide for a somewhat logical perspective of the fundamentals, development, and state-of-the-art applications of high strain-rate and shock phenomena.

Download or read book Strain Rate and Strain Rate History Effects in Two Mild Steels written by M. L. Wilson and published by . This book was released on 1979 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented of a series of experiments performed with two steels to investigate the dependence of flow stress on strain rate and its history. For this purpose quasi-static, dynamic and incremental strain rate tests were conducted on SAE 1020 hot-rolled steel and SAE 1018 cold-rolled steel at room temperature. It is shown that while the flow stress of both steels exhibits a significant strain rate sensitivity, the effect of strain rate history is relatively small in comparison with that generally found in fcc and hcp metals. A comparison is made with results of the work of other investigators. (Author).

This book was released on 1969 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program has been to elucidate the fundamental mechanisms of high-rate plastic deformation of metals. Single crystal specimens of an fcc metal (Cu) and a bcc metal (Nb) were deformed; the macroscopic yielding behavior was noted for each material as a function of strain rate, and the structures of the deformed crystals were studied by metallographic techniques. In addition to the single-crystal work, a study was made of the character of slip bands in polycrystalline iron and a mild steel as a function of temperature. This permitted comparisons to be made between the behavior of different bcc metals. (Author).
