Download or read book The Rate Dependence of Structure Evolution in Copper and Its Influence on the Stress strain Behavior at Very High Strain Rates written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A model for the deformation of copper over a wide range of strain rates has been modified to account for the contribution of dislocation drag at high strain rates. The main effect of adding this mechanism is found in the near yield region at strain rates exceeding 103 s−1. However, even at strain rates as high as 106 s−1 the rate controlling deformation mechanism at strains greater than roughly epsilon=0.1 is thermal activation. It is postulated that the high stresses predicted at yield when the strain rates are raised above 103 s−1 may lead to the rapid dislocation accumulation rates that have been found experimentally and which lead to the increased strain-rate sensitivity reported to copper and other metals at these strain rates.

Download or read book Fundamentals of Strength written by Paul S. Follansbee and published by John Wiley & Sons. This book was released on 2014-03-03 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offers data, examples, and applications supporting the use of the mechanical threshold stress (MTS) model Written by Paul S. Follansbee, an international authority in the field, this book explores the underlying theory, mechanistic basis, and implementation of the mechanical threshold stress (MTS) model. Readers are introduced to such key topics as mechanical testing, crystal structure, thermodynamics, dislocation motion, dislocation–obstacle interactions, hardening through dislocation accumulation, and deformation kinetics. The models described in this book support the emerging theme of Integrated Computational Materials Engineering (ICME) by offering a foundation for the bridge between length scales characterizing the mesoscale (mechanistic) and the macroscopic. Fundamentals of Strength begins with a chapter that introduces various approaches to measuring the strength of metals. Next, it covers: Structure and bonding Contributions to strength Dislocation–obstacle interactions Constitutive law for metal deformation Further MTS model developments Data analysis: deriving MTS model parameters The next group of chapters examines the application of the MTS model to copper and nickel, BCC metals and alloys, HCP metals and alloys, austenitic stainless steels, and heavily deformed metals. The final chapter offers suggestions for the continued development and application of the MTS model. To help readers fully understand the application of the MTS model, the author presents two fictional materials along with extensive data sets. In addition, end-of-chapter exercises give readers the opportunity to apply the models themselves using a variety of data sets. Appropriate for both students and materials researchers, Fundamentals of Strength goes beyond theory, offering readers a model that is fully supported with examples and applications.

Download or read book Fundamentals of Strength written by Paul Follansbee and published by Springer Nature. This book was released on 2022-07-28 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition updates and expands on the class-tested first edition text, augmenting discussion of dynamic strain aging and austenitic stainless steels and adding a section on analysis of nickel-base superalloys that shows how the mechanical threshold stress (MTS) model, an internal state variable constitutive formulation, can be used to de-convolute synergistic effects. The new edition retains a clear and rigorous presentation of the theory, mechanistic basis, and application of the MTS model. Students are introduced to critical competencies such as crystal structure, dislocations, thermodynamics of slip, dislocation–obstacle interactions, deformation kinetics, and hardening through dislocation accumulation. The model described in this volume facilitates readers’ understanding of integrated computational materials engineering (ICME), presenting context for the transition between length scales characterizing the mesoscale (mechanistic) and the macroscopic. Presenting readers a model buttressed by detailed examples and applications, the textbook is ideal for students, practitioners, and materials researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Significant progress in the science and technology of the mechanical behaviour of materials has been made in recent years. The greatest strides forward have occurred in the field of advanced materials with high performance, such as ceramics, composite materials, and intermetallic compounds. The Sixth International Conference on Mechanical Behaviour of Materials (ICM-6), taking place in Kyoto, Japan, 29 July - 2 August 1991 addressed these issues. In commemorating the fortieth anniversary of the Japan Society of Materials Science, organised by the Foundation for Advancement of International Science and supported by the Science Council of Japan, the information provided in these proceedings reflects the international nature of the meeting. It provides a valuable account of recent developments and problems in the field of mechanical behaviour of materials.

This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A recently developed model for the deformation of copper is reviewed. The model separates the kinetics of structure evolution from those at constant structure and uses the mechanical threshold stress (yield stress at 0°K) as an internal-state variable. Predictions of the stress-strain behavior at high strain rates are compared with experimental results, and the potential application of the modeling procedure in the shock-wave regime is discussed.
