Cambridge University Press 978-0-521-86436-7 — Theory of Dislocations Peter M. Anderson , John P. Hirth , Jens Lothe Frontmatter More Information i Theory of Dislocations Third Edition Theory of Dislocations offers coverage of the fundamentals of line defects called disloca- tions, with applications to speciic metallic and ionic crystals. Step-by- step developments offer an in- depth understanding of the topic and a solid theoretical foundation from which to develop modeling and computational approaches to discrete dislocation plasticity. Important experimental observations related to the effects of crystal structure, temperature, nucleation mechanisms, and speciic systems are discussed. This new edition incorporates margin notes and extensive chapter summaries that highlight key concepts and develop- ments. New topics include a tensorial description of dislocation content, disconnection properties, curvature induced by dislocations, lattice Green's functions, conserved integrals, multipole representations of dislocations, stability of junctions, and discrete dislocation dynamics simulations. Each of the twenty-three chapters begins with a striking image and narrative from an international researcher that highlights a key advance or breakthrough. The text is suitable for graduate and advanced undergraduate study and includes problems at the end of each chapter. Peter M. Anderson received his ScB degree in Engineering from Brown University in 1981 and his ScM and PhD degrees in Applied Sciences from Harvard University in 1982 and 1986, respectively. Following a two- year postdoctoral fellowship at Cambridge University (UK), he joined The Ohio State University where he is currently Professor and Chair in the Department of Materials Science and Engineering. He has authored/ coauthored over one hundred articles on mechanical behavior of bulk and thin ilm materials, including a chap- ter on crystal plasticity in “Fundamentals of Metal Forming” and a set of over three hun- dred PowerPoint lecture slides that serve as an instructors’ resource for the introductory textbook, Materials Science and Engineering: An Introduction. He has held visiting positions at Brown University, National Institute of Standards and Technology, Ruhr-Universität Bochum, and Los Alamos National Laboratory, where he was Bernd T. Matthias Scholar. He is recipient of an Ofice of Naval Research Young Investigator Award, three- time recipient of the Boyer Award for Teaching Innovation, and a recipient of the Lumley Research Award. Professor John Price Hirth received his undergraduate degree from The Ohio State University in 1953 and his PhD from Carnegie Mellon University (then Carnegie Institute of Technology) in 1957. He taught at the latter institution for a short period after a postdoctor- ate year at Bristol University. He was then a professor at The Ohio State University through 1988 and at Washington State University 1988–1999, when he retired to Arizona, remain- ing afiliated with Los Alamos National Laboratory. His research has been in the areas of dislocation theory, phase transformations, and mechanical properties. In addition to many scientiic articles, he has been the coauthor of two books on these subjects. He has received a number of awards recognizing his work and is a member of the National Academy of Engineering (since 1974) and National Academy of Science (since 1994). Jens Lothe (deceased) was born in Oslo 1931 and studied physics at UiO (University of Oslo), where he received the cand. real. degree in 1956 and the dr. philos. degree in 1968. Positions at UiO included research assistant (1956– 1959); lecturer (1959– 1963); associate professor (dosent) (1963– 1972); and professor (1972– 1992). Positions while on leave from UiO included Norwegian Research Council Student at University of Bristol (1957–1958), Assistant Professor at Carnegie Institute of Technology (now Carnegie- Mellon University) (1960– 1962), and Battelle Visiting Professor at The Ohio State University (1965–1966). Professor Lothe’s research interests included nucleation theory, dislocation theory, and elastic wave theory for anisotropic media. Lothe was author or coauthor of approximately 120 papers. He was coauthor (with J. Hirth) of previous editions of Theory of Dislocations (irst edition, 1968; second edition, 1982; reprint edition, 1992). He coedited/authored (with V. L. Indenbom) Elastic Strain Fields and Dislocation Mobility, volume 31 of the series Modern Problems in Condensed Matter Sciences (1992). Lothe was a member of the Norwegian Academy of Science and Letters (since 1973). © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-0-521-86436-7 — Theory of Dislocations Peter M. Anderson , John P. Hirth , Jens Lothe Frontmatter More Information ii About the Book Cover The book cover image is the product of a competition among students and fac- ulty in the Department of Materials Science and Engineering at The Ohio State University (OSU). The objective was to create the illusion that the book itself is a dislocated crystal. The quality and number of entries received was enhanced by the adoption in 2012 of a three-semester undergraduate sequence in modeling and simulation and a graduate core course in computational materials science, taught by a cadre of faculty: Peter Anderson, Maryam Ghazisaeidi, Stephen Niezgoda, Alison Polasik, Wolfgang Windl, and Ji- Cheng Zhao. The winning image, created by third- year graduate student Daniel Buey, provides a perspective view along the core of an edge dislocation in a simple cubic crystal. The view along the spine gives the illusion that the book is only one unit cell thick. CrystalMaker software was used to create an undistorted simple cubic structure. A dislocation was then inserted by displacing the atoms according to the Volterra solution for an edge dislocation (see Eqs. 3.47, 3.48). © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-0-521-86436-7 — Theory of Dislocations Peter M.
