This book is intended primarily as a teaching text, as well as a reference for individual study in the behavior of thin walled structural components. Such structures are widely used in the engineering profession for spacecraft, missiles, aircraft, land-based vehicles, ground structures, ocean craft, underwater vessels and structures, pressure vessels, piping, chemical processing equipment, modern housing, etc. It presupposes that the reader has already completed one basic course in the mechanics or strength of materials. It can be used for both undergraduate and graduate courses. Since beams (columns, rods), plates and shells comprise components of so many of these modern structures, it is necessary for engineers to have a working knowledge of their behavior when these structures are subjected to static, dynamic (vibration and shock) and environmental loads. Since this text is intended for both teaching and self-study, it stresses fundamental behavior and techniques of solution. It is not an encyclopedia of all research or design data, but provides the reader the wherewithal to read and study the voluminous literature. Chapter 1 introduces the three-dimensional equations oflinear elasticity, deriving them to the extent necessary to treat the following material. Chapter 2 presents, in a concise way, the basic assumptions and derives the governing equations for classical Bernoulli-Euler beams and plates in a manner that is clearly understood.

This is the first book to integrate the theory, design, and stability analysis of plates and shells in one comprehensive volume. With authoritative accounts of diverse aspects of plates and shells, this volume facilitates the study and design of structures that incorporate both plate and shell components. Drawing on his extensive experience in plate and shell theory and design, the author: --introduces the principles and applications of bending of plates; membrane theory and bending of shells; and stability of plates and shells; --explains the crucial elements of roof structure analysis and finite element formulations; --explores topics of current interest, such as plastic design of plates and approximate solution of membrane stress in shells of revolution and in buckling of shells; --describes how to select design approaches according to the functional and safety requirements of specific structures. Each chapter demonstrates the principles, practical applications, and design of a plate or shell component using real-life examples, providing the reader with an in-depth, unified understanding of the theory and function of the component. Chapters are written to be as independent of each other as possible to allow for selective reading on either plates or shells. In addition, the text is conveniently supplemented by appendices of Fourier Series and Bessel Functions. Integrating the fundamental and applied aspects of plate and shell theory, this volume serves as an essential text for graduate students and as an easy-to-use reference for engineers in mechanical, civil, and aeronautical engineering.

Author: Maan H. Jawad | Size: 8 MB | Format:PDF | Quality:Unspecified | Publisher: American Society of Mechanical Engineers | Year: 2003 | pages: 476 | ISBN: 0791801993, 9780791801994
OVERVIEW This book is written primarily for professional engineers interested in designing plate and shell structures. It covers basic aspects of theories and gives examples for the design of components due to internal and external loads as well as other loads such as wind and dead loads. Various derivations are kept relatively simple and the resultant equations are simplified to a level where the engineer may apply them directly to design problems. More elaborate derivations and more general equations may be found in the literature for those interested in a more in-depth knowledge of the theories of plates and shells. The examples given throughout this book are intended to show the engineer the level of analysis needed to achieve a safe design based on a given required degree of accuracy. This book is also appropriate for advanced engineering courses.

Traffic Flow Dynamics: Data, Models and Simulation
Author: Martin Treiber, Arne Kesting and Christian Thiemann | Size: 19 MB | Format:PDF | Quality:Unspecified | Publisher: Springer | Year: 2013 | pages: 500 | ISBN: 3642324592, 9783642324598, 9783642324604
This textbook provides a comprehensive and instructive coverage of vehicular traffic flow dynamics and modeling. It makes this fascinating interdisciplinary topic, which to date was only documented in parts by specialized monographs, accessible to a broad readership.
Numerous figures and problems with solutions help the reader to quickly understand and practice the presented concepts. This book is targeted at students of physics and traffic engineering and, more generally, also at students and professionals in computer science, mathematics, and interdisciplinary topics. It also offers material for project work in programming and simulation at college and university level.
The main part, after presenting different categories of traffic data, is devoted to a mathematical description of the dynamics of traffic flow, covering macroscopic models which describe traffic in terms of density, as well as microscopic many-particle models in which each particle corresponds to a vehicle and its driver. Focus chapters on traffic instabilities and model calibration/validation present these topics in a novel and systematic way. Finally, the theoretical framework is shown at work in selected applications such as traffic-state and travel-time estimation, intelligent transportation systems, traffic operations management, and a detailed physics-based model for fuel consumption and emissions.

Constructive, practical approach of spectral solutions to non-standard differential problems
Numerous and varied examples assist the reader in smoothly understanding and learning
Text shows what kind of spectral method works for a particular problem and how it can be efficiently implemented
Less academic examples but more real examples from elasticity and hydrodynamics
Complete solutions for classical Mathieu’s system as a multi parameter eigenvalue problem, i.e., in its natural setting
This book focuses on the constructive and practical aspects of spectral methods. It rigorously examines the most important qualities as well as drawbacks of spectral methods in the context of numerical methods devoted to solve non-standard eigenvalue problems. In addition, the book also considers some nonlinear singularly perturbed boundary value problems along with eigenproblems obtained by their linearization around constant solutions.
The book is mathematical, poising problems in their proper function spaces, but its emphasis is on algorithms and practical difficulties. The range of applications is quite large. High order eigenvalue problems are frequently beset with numerical ill conditioning problems. The book describes a wide variety of successful modifications to standard algorithms that greatly mitigate these problems.
In addition, the book makes heavy use of the concept of pseudospectrum, which is highly relevant to understanding when disaster is imminent in solving eigenvalue problems. It also envisions two classes of applications, the stability of some elastic structures and the hydrodynamic stability of some parallel shear flows.
This book is an ideal reference text for professionals (researchers) in applied mathematics, computational physics and engineering. It will be very useful to numerically sophisticated engineers, physicists and chemists. The book can also be used as a textbook in review courses such as numerical analysis, computational methods in various engineering branches or physics and computational methods in analysis.

IRC: 37-2012 Guidelines for The Design of Flexible Pavements (3rd Revision)
Size: 4.6 MB | Format:PDF | Quality:Original preprint | Publisher: Indian Roads Congress | Year: July, 2012 | pages: 94
SCOPE OF THE GUIDELINES
The Guidelines shall apply to the design of new flexible pavements for Expressways, National Highways, State Highways, Major District Roads and other categories of roads predominantly carrying motorized vehicles. These guidelines do not form a rigid standard and sound engineering judgment considering the local environment and past pavement performance in the respective regions should be given due consideration while selecting a pavement composition.
For the purpose of the guidelines, flexible pavements include pavements with Bituminous surfacing over:
(i) Granular base and sub-base
(ii) Cementitious bases and sub-bases with a crack relief layer of aggregate interlayer below the bituminous surfacing
(iii) Cementitious bases and sub-bases with SAMI in-between bituminous surfacing and the cementitious base layer for retarding the reflection cracks into the bituminous layer
(iv) Reclaimed Asphalt Pavement (RAP) with or without addition of fresh aggregates treated with foamed bitumen/bitumen emulsion
(v) Use of deep strength long life bituminous pavement
These guidelines shall not be straightway applied to overlay design for which IRC 81-997 or a more suitable procedure based on evaluation of in situ properties of pavement layers by Falling Weight Deflectometer (FWD) should be used (25,56).
