• 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.

  • A look at engineering education today- with an eye to tomorrow Engineering education is in flux. While it is increasingly important that engineers be innovative, entrepreneurial, collaborative, and able to work globally, there are virtually no programs that prepare students to meet these new challenges. Shaping Our World: Engineering Education for the 21st Century seeks to fill this void, exploring revolutionary approaches to the current engineering curriculum that will bring it fully up to date and prepare the next generation of would-be engineers for real and lasting professional success. Comprised of fourteen chapters written by respected experts on engineering education, the book is divided into three parts that address the need for change in the way engineering is taught; specific innovations that have been tested, why they matter, and how they can be more broadly instituted; and the implications for further changes. Designed to aid engineering departments in their transition towards new modes of learning and leadership in engineering education, the book describes how to put into practice educational programs that are aligned with upcoming changes, such as those proposed in the NAE's Engineer of 2020 reports. Addressing the need to change engineering education to meet the demands of the 21st century head on, Shaping Our World condenses current discussions, research, and trials regarding new methods into specific, actionable calls for change.

  • Currently, recycling of e-waste can be broadly divided into three major steps: (a) disassembly: selectively disassembly, targeting on singling out hazardous or valuable components for special treatment, is an indispensable process in recycling of e-waste; (b) upgrading: using mechanical processing and/or metallurgical processing to up-grade desirable materials content, i.e. preparing materials for refining process, such as grinding the plastics into powders; (c) refining: in the last step, recovered materials are retreated or purified by using metallurgical processing so as to be acceptable for their original using. Four topical areas are planned including one special session on the recycling of batteries. Papers in the following topics will be welcomed: Mechanical recycling of E-Wastes Recycling of plastics from E-Wastes Recovery of metals from E-wastes Hydrometallurgical recycling (leaching) of E-Wastes Combustion or pyrolysis of E-Wastes Life cycle and economic analysis for the recycling of E-Wastes

  • This biography highlights the achievements of America's first professional degreed female scientist, Ellen Swallow Richards (1842--1911). The book takes the reader from Richards's childhood on a Massachusetts farm where she was schooled at home, to her internationally renowned successes in multiple branches of science. o Schools, colleges, and libraries are searching for more books about remarkable, successful women. Richards paved the way for women to enter numerous fields of science previously believed to be the domain of men.
    o Currently there is much emphasis on nutrition; Richards pioneered in this field, teaching the American public about fats, carbohydrates, proteins and calories at a time when scarcely anyone knew of their importance.
    o Ellen Swallow Richards pioneered multiple fields of science and technology, opening doors for women to become chemists, biologists, geologists, ecologists, nutritionists, dietitians, science teachers, professors, and home economists.
    o Richards began the ecology movement, particularly relevant in today's world as more and more attention is being paid to the health of our planet.
