Free Download Freezing of Lakes and the Evolution of Their Ice Cover, Second Edition by Matti Leppäranta English | EPUB (True) | 2023 | 365 Pages | ISBN : 3031256042 | 109.9 MB This book updates the first edition for the status of knowledge in the physics of lake ice and the interactions between the ice cover and the liquid water underneath. Since the first edition was written in 2013, there has been a lot of progress in the field, in particular concerning environmental questions and the impact of climate change. Life conditions in ice-covered lakes and practical matters are now brought more into the picture so that the revision also properly serves as a handbook for applications. The author has worked widely with boreal lakes, polar lakes and Central Asian lakes that provides a wide geographical spectrum.  Free Download Free-Convective Heat Transfer: With Many Photographs of Flows and Heat Exchange by Oleg G. Martynenko , Pavel P. Khramtsov English | PDF (True) | 2005 | 520 Pages | ISBN : 3540250018 | 24.3 MB Free Convective Heat Transfer is a thorough survey of various kinds of free-convective flows and heat transfer. Reference data are accompanied by a large number of photographs originating from different optical visualization methods illustrating the different types of flow. The formulas derived from numerical and analytical investigations are valuable tools for engineering calculations. They are written in their most compact and general form in order to allow for an extensive range of different variants of boundary and initial conditions, which, in turn, leads to a wide applicability to different flow types. Some specific engineering problems are solved in the book as exemplary applications of these formulas.  Free Download Frames and Locales: Topology without points by Jorge Picado , Aleš Pultr English | PDF (True) | 2012 | 412 Pages | ISBN : 303480153X | 3.9 MB Until the mid-twentieth century, topological studies were focused on the theory of suitable structures on sets of points. The concept of open set exploited since the twenties offered an expression of the geometric intuition of a "realistic" place (spot, grain) of non-trivial extent.  Free Download Fracture Mechanics by Dominique P. Miannay English | PDF | 1998 | 356 Pages | ISBN : 0387982426 | 41 MB Intended for engineers from a variety of disciplines that deal with structural materials, this text describes the current state of knowledge of how fractures in materials form and propagate, leading to failure. The book begins by describing the fracture process at the two extremes of scale: first in the context of atomic structures, then in terms of a continuous elastic medium. Treating the fracture process in increasingly sophisticated ways, the book then considers plastic corrections and the procedures for measuring the toughness of materials. Practical considerations are then discussed, including crack propagation, geometry dependence, flaw density, mechanisms of failure by cleavage, the ductile-brittle transition, and continuum damage mechanics. The text concludes with discussions of generalized plasticity and the link between the microscopic and macroscopic aspects. The text is suitable for advanced undergraduates. Problems are provided at the end of each chapter.  Free Download Fracture Mechanics: With an Introduction to Micromechanics by Dietmar Gross , Thomas Seelig English | PDF | 2006 | 324 Pages | ISBN : 3642063160 | 6.2 MB Concerned with the fundamental concepts and methods of fracture mechanics and micromechanics, Fracture Mechanics primarily focuses on the mechanical description of fracture processes; however, material specific aspects are also discussed.  Free Download Fracture Mechanics: With an Introduction to Micromechanics, Second Edition by Dietmar Gross , Thomas Seelig English | PDF (True) | 2011 | 342 Pages | ISBN : 3642192394 | 4.9 MB Concerned with the fundamental concepts and methods of fracture mechanics and micromechanics, Fracture Mechanics primarily focuses on the mechanical description of the fracture process; however, material specific aspects are also discussed. The presentation of continuum mechanical and phenomenological foundations is followed by an introduction into classical failure hypotheses. A major part of the book is devoted to linear elastic and elastic-plastic fracture mechanics. Further subjects are creep fracture, dynamic fracture mechanics, damage mechanics, probabilistic fracture mechanics, failure of thin films and fracture of piezoelectric materials. The book also contains an extensive introduction into micromechanics. Self-contained and well-illustrated, this text serves as a graduate-level text and reference.  Free Download Fracture Mechanics by Alan T. Zehnder English | PDF | 2012 | 234 Pages | ISBN : 9400725949 | 3.5 MB Fracture mechanics is a vast and growing field. This book develops the basic elements needed for both fracture research and engineering practice. The emphasis is on continuum mechanics models for energy flows and crack-tip stress- and deformation fields in elastic and elastic-plastic materials. In addition to a brief discussion of computational fracture methods, the text includes practical sections on fracture criteria, fracture toughness testing, and methods for measuring stress intensity factors and energy release rates. Class-tested at Cornell, this book is designed for students, researchers and practitioners interested in understanding and contributing to a diverse and vital field of knowledge.  Free Download Foundations of Solid Mechanics by P. Karasudhi English | PDF | 1991 | 458 Pages | ISBN : 0792307720 | 27 MB This book has been written with two purposes, as a textbook for engineering courses and as a reference book for engineers and scientists. The book is an outcome of several lecture courses. These include lectures given to graduate students at the Asian Institute of Technology for several years, a course on elasticity for University of Tokyo graduate students in the spring of 1979, and courses on elasticity, viscoelasticity and ftnite deformation at the National University of Singapore from May to November 1985. In preparing this book, I kept three objectives in mind: ftrst, to provide sound fundamental knowledge of solid mechanics in the simplest language possible; second, to introduce effective analytical and numerical solution methods; and third, to impress on readers that the subject is beautiful, and is accessible to those with only a standard mathematical background. In order to meet those objectives, the ftrst chapter of the book is a review of mathematical foundations intended for anyone whose background is an elementary knowledge of differential calculus, scalars and vectors, and Newton's laws of motion. Cartesian tensors are introduced carefully. From then on, only Cartesian tensors in the indicial notation, with subscript as indices, are used to derive and represent all theories.  Free Download Foundations of Nanomechanics: From Solid-State Theory to Device Applications by Andrew N. Cleland English | PDF | 2003 | 440 Pages | ISBN : 3540436618 | 40.2 MB Why write another book on mechanics? There are, after all, a number of excellent texts that describe in great detail the way classical solids behave when acted upon by static and time-varying forces; many of these are cited in this monograph. These texts treat solids as continuous objects, and quantum mechanics does not enter the discussion. Furthermore, the atomic nature of the solid is implicit, but does not enter in a central role. At the other end of the spectrum, texts on condensed matter physics focus on the quantum mechanical nature of the solid; these contain quite clear descriptions of acou stic waves in solids, describing their dynamic and thermal properties, and how they interact with electrons in the solid, but contain little information regarding bulk deformations. This text, focussing on the mechanics of very small objects, attempts to provide a link between these two approaches; in addition to describing the theories of both the classical and the quantum mechanical solid, I attempt to outline where the classical description breaks down, and quantum mechanics must be applied, to understand the behavior of a nanoscale object. I have tried to merge the continuum description of the solid with the atomic one, and to show how and where quantum mechanics plays a role, especially as the size scale of the system is reduced, making the quantized energy scale larger and the role of thermal vibrations more important.  Free Download Foundations of Fluid Mechanics with Applications: Problem Solving Using Mathematica® by Sergey P. Kiselev , Evgenii V. Vorozhtsov , Vasily M. Fomin English | PDF | 1999 | 587 Pages | ISBN : 0817639950 | 42.2 MB Fluid mechanics (FM) is a branch of science dealing with the investi gation of flows of continua under the action of external forces. The fundamentals of FM were laid in the works of the famous scientists, such as L. Euler, M. V. Lomonosov, D. Bernoulli, J. L. Lagrange, A. Cauchy, L. Navier, S. D. Poisson, and other classics of science. Fluid mechanics underwent a rapid development during the past two centuries, and it now includes, along with the above branches, aerodynamics, hydrodynamics, rarefied gas dynamics, mechanics of multi phase and reactive media, etc. The FM application domains were expanded, and new investigation methods were developed. Certain concepts introduced by the classics of science, however, are still of primary importance and will apparently be of importance in the future. The Lagrangian and Eulerian descriptions of a continuum, tensors of strains and stresses, conservation laws for mass, momentum, moment of momentum, and energy are the examples of such concepts and results. This list should be augmented by the first and second laws of thermodynamics, which determine the character and direction of processes at a given point of a continuum. The availability of the conservation laws is conditioned by the homogeneity and isotrop icity properties of the Euclidean space, and the form of these laws is related to the Newton's laws. The laws of thermodynamics have their foundation in the statistical physics. |
