Author: Barry Kean Atkinson Publisher: Elsevier ISBN: 1483292746 Category : Science Languages : en Pages : 547
Book Description
The analysis of crack problems through fracture mechanics has been applied to the study of materials such as glass, metals and ceramics because relatively simple fracture criteria describe the failure of these materials. The increased attention paid to experimental rock fracture mechanics has led to major contributions to the solving of geophysical problems.The text presents a concise treatment of the physics and mathematics of a representative selection of problems from areas such as earthquake mechanics and prediction, hydraulic fracturing, hot dry rock geothermal energy, fault mechanics, and dynamic fragmentation.

Book Description
Scientific understanding of fluid flow in rock fractures--a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storage--has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.

Book Description
The purpose of this book is to acquaint the geoscientist with issues associated with the debate over orientation and magnitude of stress in the lithosphere. Terry Engelder provides a broad understanding of the topic, while touching some of the specific details involved in the interpretation of stress data generated by the most commonly used measurement techniques. An understanding of stress in the lithosphere starts with an introduction to nomenclature based on three reference states of stress. Since rock strength governs differential stress magnitudes, stress regimes are identified according to the specific failure mechanism (crack propagation, shear rupture, ductile flow, or frictional slip) that controls the magnitude of stress at a particular time and place in the lithosphere. After introducing the various stress regimes, the author shows how their extent in the upper crust is demarcated by direct measurements of four types: hydraulic fracture, borehole-logging, strain-relaxation, and rigid-inclusion measurements. The relationship between lithospheric stress and the properties of rocks is then presented in terms of microcrack-related phenomena and residual stress. Lithospheric stress is also inferred from the analysis of earthquakes. Finally, lithospheric stress is placed in the context of large-scale stress fields and plate tectonics. Originally published in 1993. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
