This book treats the mechanics of porous materials infiltrated with a fluid (poromechanics), focussing on its linear theory (poroelasticity). Porous materials from inanimate bodies such as sand, soil and rock, living bodies such as plant tissue, animal flesh, or man-made materials can look very different due to their different origins, but as readers will see, the underlying physical principles governing their mechanical behaviors can be the same, making this work relevant not only to engineers but also to scientists across other scientific disciplines.
Readers will find discussions of physical phenomena including soil consolidation, land subsidence, slope stability, borehole failure, hydraulic fracturing, water wave and seabed interaction, earthquake aftershock, fluid injection induced seismicity and heat induced pore pressure spalling as well as discussions of seismoelectric and seismoelectromagnetic effects. The work also explores the biomechanics of cartilage, bone and blood vessels.
Chapters present theory using an intuitive, phenomenological approach at the bulk continuum level, and a thermodynamics-based variational energy approach at the micromechanical level. The physical mechanisms covered extend from the quasi-static theory of poroelasticity to poroelastodynamics, poroviscoelasticity, porothermoelasticity, and porochemoelasticity. Closed form analytical solutions are derived in details. Β
This book provides an excellent introduction to linear poroelasticity and is especially relevant to those involved in civil engineering, petroleum and reservoir engineering, rock mechanics, hydrology, geophysics, and biomechanics.

ΒThe author is to be commended for introducing a chapter on the gauge theory of fluid mechanics, which is quite scarce in fluid mechanics books . . . the book can serve as an excellent introduction for graduate students in applied mathematics and physics who are interested in pursuing research in specific areas of fluid mechanics . . . One of the strengths of the book is its culmination in a detailed solution to all the problems.Β Choice ΒThis book contains an excellent basic presentation of theory, applications, and methods of solutions for various problems of classical and modern fluid dynamics.Β Zentralblatt Math This textbook describes the fundamental ΒphysicalΒ aspects of fluid flows for beginners of fluid mechanics in physics, mathematics and engineering, from the point of view of modern physics. It also emphasizes the dynamical aspects of fluid motions rather than the static aspects, illustrating vortex motions, waves, geophysical flows, chaos and turbulence. Beginning with the fundamental concepts of the nature of flows and the properties of fluids, the book presents fundamental conservation equations of mass, momentum and energy, and the equations of motion for both inviscid and viscous fluids. In addition to the fundamentals, this book also covers water waves and sound waves, vortex motions, geophysical flows, nonlinear instability, chaos, and turbulence. Furthermore, it includes the chapters on superfluids and the gauge theory of fluid flows. The material in the book emerged from the lecture notes for an intensive course on Elementary Fluid Mechanics for both undergraduate and postgraduate students of theoretical physics given in 2003 and 2004 at the Nankai Institute of Mathematics (Tianjin) in China. Hence, each chapter may be presented separately as a single lecture.

This book stems from a course on Micromechanics that I started about fifteen years ago at Northwestern University. At that time, micromechanics was a rather unfamiliar subject. Although I repeated the course every year, I was never convinced that my notes have quite developed into a final manuscript because new topics emerged constantly requiring revisions, and additions. I finally came to realize that if this is continued, then I will never complete the book to my total satisfaction. Meanwhile, T. Mori and I had coauthored a book in Japanese, entitled Micromechanics, published by Baifu-kan, Tokyo, in 1975. It received an extremely favorable response from students and reΒ searchers in Japan. This encouraged me to go ahead and publish my course notes in their latest version, as this book, which contains further development of the subject and is more comprehensive than the one published in Japanese. Micromechanics encompasses mechanics related to microstructures of materials. The method employed is a continuum theory of elasticity yet its applications cover a broad area relating to the mechanical behavior of materiΒ als: plasticity, fracture and fatigue, constitutive equations, composite materiΒ als, polycrystals, etc. These subjects are treated in this book by means of a powerful and unified method which is called the 'eigenstrain method. ' In particular, problems relating to inclusions and dislocations are most effectively analyzed by this method, and therefore, special emphasis is placed on these topics.

BASIC Hydraulics aims to help students both to become proficient in the BASIC programming language by actually using the language in an important field of engineering and to use computing as a means of mastering the subject of hydraulics. The book begins with a summary of the technique of computing in BASIC together with comments and listing of the main commands and statements. Subsequent chapters introduce the fundamental concepts and appropriate governing equations. Topics covered include principles of fluid mechanics; flow in pipes, pipe networks and open channels; hydraulic machinery; and seepage and groundwater flow. Each chapter provides a series of worked examples consisting primarily of an introduction in which the general topic or specific problem to be considered is presented. A program capable of solving the problem is then given, together with examples of the output, sometimes for several different sets of conditions. Finally, in a section headed Program Notes the way the program is constructed and operates is explained, and the engineering lessons to be learned from the program output are indicated. Each chapter also concludes with a set of problems for the student to attempt. This book is mainly intended for the first- and second-year undergraduate student of civil engineering who will be concerned with the application of fundamental fluid mechanics theory to civil engineering problems.

Manual on Scour at Bridges and Other Hydraulic Structures (CIRIA)
Author(s)/Editor(s): R. May , J. C. Ackers , A. Kirby | Size: 16 MB | Format:PDF | Quality:Scanner | Publisher: Construction Industry Research & Information Association (CIRIA) | Year: 2002 | pages: 226 | ISBN: 0860175510 / 978-0860175513
Structures built in or near rivers and other channels can be vulnerable to scour around their foundations. If the depth of the scour becomes significant, the stability of the foundations may be endangered, with a consequent risk of damage or failure of the structure. In the past 15 years, there have been several bridge failures, resulting in transport disruption, economic loss and, on occasion, loss of life. Some of these failures are included in the manual's summary case studies. The factors influencing scour are complex and vary according to the type of structure. Protection works for preventing scour need to be designed to withstand the flow forces imposed on them and have to be practicable to build and install, while minimising adverse environmental effects. The manual therefore considers scour processes, estimating and assessing scour, protective measures, monitoring, environmental factors, risk assessments, and cost and benefit analyses. This manual is intended for engineers engaged in the design, construction, operation and maintenance of structures in the water environment that may be subject to scour of erodible beds or banks. It is equally relevant to UK and worldwide scour problems, and to new as well as existing structures.

The development of water resources has proceeded at an amazing speed around the world in the last few decades. The hydraulic engineer has played his part: in constructing much larger artificial channels than ever before, larger and more sophisticated control structures, and systems of irrigation, drainage and water supply channels in which the flow by its nature is complex and unsteady requiring computer-based techniques at both the design and operation stage. It seemed appropriate to look briefly at some of the developments in hydraulic design resulting from this situation. Hence the idea of the Conference was formed. The Proceedings of the Conference show that hydraulic engineers have been able to acquire a very substantial base of design capability from the experience of the period referred to. The most outstanding development to have occurred is in the combination of physical and mathematical modelling, which in hydraulic engineering has followed a parallel path to that in other branches of engineering science. The Proceedings of this Conference will give to the reader an awareness of the current state of hydraulic design in open channel flow and open channel control structures.
