Nonlinear Theory of Elastic Plates provides the theoretical
materials necessary for the three plate models-Cosserat plates,
Reissner-Mindlin plates and Kirchhoff-Love plates- in the context
of finite elastic deformations. One separate chapter is devoted to
the linearized theory of Kirchhoff-Love plates, which allows for
the study of vibrations of a pre-stressed plate and the static
buckling of a plate. All mathematical results in the tensor theory
in curvilinear coordinates necessary to investigate the plate
theory in finite deformations are provided, making this a
self-contained resource.
This book analyzes several compliant contact force models within
the context of multibody dynamics, while also revisiting the main
issues associated with fundamental contact mechanics. In
particular, it presents various contact force models, from linear
to nonlinear, from purely elastic to dissipative, and describes
their parameters. Addressing the different numerical methods and
algorithms for contact problems in multibody systems, the book
describes the gross motion of multibody systems by using a
two-dimensional formulation based on the absolute coordinates and
employs different contact models to represent contact-impact
events. Results for selected planar multibody mechanical systems
are presented and utilized to discuss the main assumptions and
procedures adopted throughout this work. The material provided here
indicates that the prediction of the dynamic behavior of mechanical
systems involving contact-impact strongly depends on the choice of
contact force model. In short, the book provides a comprehensive
resource for the multibody dynamics community and beyond on
modeling contact forces and the dynamics of mechanical systems
undergoing contact-impact events.
Pipeline engineers, operators, and plant managers are responsible
for the safety of pipelines, facilities, and staying on top of
regulatory compliance and maintenance. However, they frequently
need reference materials to support their decision, and many new
pipeline engineers and plant managers are responsible for major
repairs and decisions yet do not have the proper reference to set a
holistic integrity plan in place. Pipeline Integrity, Second
Edition delivers necessary pipeline inspection methods,
identification of hazard mechanisms, risk and consequence
evaluations, and repair strategies. Covering relevant standards and
processes for risk, assessment, and integrity management, this
go-to reference provides the principles that guide these concepts
enhanced with more critical regulatory information and easier
organization betwen liquid and gas pipelines. More detailed
information is provided on asset reliability, including risk-based
inspection and other inspection prioritizing tools such as
value-driven maintenance and evidence-based asset management.
Pipeline Integrity, Second Edition continues to provide engineers
and plants managers a vital resource for keeping their pipelines
and facilities safe and efficient.
This book investigates the performance limitation issues in
networked feedback systems. The fact that networked feedback
systems consist of control and communication devices and systems
calls for the integration of control theory and information theory.
The primary contributions of this book lie in two aspects: the
newly-proposed information-theoretic measures and the
newly-discovered control performance limitations. We first propose
a number of information notions to facilitate the analysis. Using
those notions, classes of performance limitations of networked
feedback systems, as well as state estimation systems, are then
investigated. In general, the book presents a unique, cohesive
treatment of performance limitation issues of networked feedback
systems via an information-theoretic approach. This book is
believed to be the first to treat the aforementioned subjects
systematically and in a unified manner, offering a unique
perspective differing from existing books.
This multi-contributed volume provides a practical,
applications-focused introduction to nonlinear acoustical
techniques for nondestructive evaluation. Compared to linear
techniques, nonlinear acoustical/ultrasonic techniques are much
more sensitive to micro-cracks and other types of small distributed
damages. Most materials and structures exhibit nonlinear behavior
due to the formation of dislocation and micro-cracks from fatigue
or other types of repetitive loadings well before detectable
macro-cracks are formed. Nondestructive evaluation (NDE) tools that
have been developed based on nonlinear acoustical techniques are
capable of providing early warnings about the possibility of
structural failure before detectable macro-cracks are formed. This
book presents the full range of nonlinear acoustical techniques
used today for NDE. The expert chapters cover both theoretical and
experimental aspects, but always with an eye towards applications.
Unlike other titles currently available, which treat nonlinearity
as a physics problem and focus on different analytical derivations,
the present volume emphasizes NDE applications over detailed
analytical derivations. The introductory chapter presents the
fundamentals in a manner accessible to anyone with an undergraduate
degree in Engineering or Physics and equips the reader with all of
the necessary background to understand the remaining chapters. This
self-contained volume will be a valuable reference to graduate
students through practising researchers in Engineering, Materials
Science, and Physics. Represents the first book on nonlinear
acoustical techniques for NDE applications Emphasizes applications
of nonlinear acoustical techniques Presents the fundamental physics
and mathematics behind nonlinear acoustical phenomenon in a simple,
easily understood manner Covers a variety of popular NDE techniques
based on nonlinear acoustics in a single volume
"A Practical Guide to Engineering Failure Investigation" has been

engineers to link their technical knowledge to the commercial
realities of working with insurers, loss adjusters and their
representatives.
This book is essential reading for consultants, expert witnesses
and all engineers who may become involved in commercial failure
investigations.
CONTENTS INCLUDE: How to use this book Professional roles and
responsibilities Strategy and tactics of failure investigation The

cause - subrogation.
This unique volume imparts practical information on the operation,
maintenance, and modernization of heavy performance machines such
as lignite mine machines, bucket wheel excavators, and spreaders.
Problems of large scale machines (mega machines) are highly
specific and not well recognized in the common mechanical
engineering environment. Prof. Rusinski and his co-authors identify
solutions that increase the durability of these machines as well as
discuss methods of failure analysis and technical condition
assessment procedures. "Surface Mining Machines: Problems in
Maintenance and Modernization" stands as a much-needed guidebook
for engineers facing the particular challenges of heavy performance
machines and offers a distinct and interesting demonstration of
scale-up issues for researchers and scientists from across the
fields of machine design and mechanical engineering.
Here's the first non-technical introduction to the exciting field
of microelectromechanical systems (MEMS). It describes in detail
the materials used in producing MEMS -- including silicon, polymers
and glass and quartz substrates -- as well as MEMS design for
nozzles, sensors, valves and other applications. It examines the
manufacture of commercial MEMS using techniques such as oxidation,
lithography, chemical vapor deposition and silicon fusion bonding
and applications in a wide range of industries including data
storage, telecommunications, consumer, automotive, medical and
defense. A unique element of this book is its look at the future of
MEMS -- its potential for microelectrode arrays, actuators and
optical switches and other technologies.
This book presents a comprehensive mathematical approach for
solving stochastic magnetic field problems. It discusses
variability in material properties and geometry, with an emphasis
on the preservation of structural physical and mathematical
properties. It especially addresses uncertainties in the computer
simulation of magnetic fields originating from the manufacturing
process. Uncertainties are quantified by approximating a stochastic
reformulation of the governing partial differential equation,
demonstrating how statistics of physical quantities of interest,
such as Fourier harmonics in accelerator magnets, can be used to
achieve robust designs. The book covers a number of key methods and
results such as: a stochastic model of the geometry and material
properties of magnetic devices based on measurement data; a
detailed description of numerical algorithms based on sensitivities
or on a higher-order collocation; an analysis of convergence and
efficiency; and the application of the developed model and
algorithms to uncertainty quantification in the complex magnet
systems used in particle accelerators.
This book gives an overview of the existing self-healing
nanotextured vascular approaches. It describes the healing agents
used in engineering self-healing materials as well as the
fundamental physicochemical phenomena accompanying self-healing.
This book also addresses the different fabrication methods used to
form core-shell nanofiber mats. The fundamental theoretical aspects
of fracture mechanics are outlined. A brief theoretical description
of cracks in brittle elastic materials is given and the Griffith
approach is introduced. The fracture toughness is described,
including viscoelastic effects. Critical (catastrophic) and
subcritical (fatigue) cracks and their growth are also described
theoretically. The adhesion and cohesion energies are introduced as
well, and the theory of the blister test for the two limiting cases
of stiff and soft materials is developed. In addition, the effect
of non-self-healing nanofiber mats on the toughening of ply
surfaces in composites is discussed. The book also presents a brief
description of the electrochemical theory of corrosion crack
growth. All the above-mentioned phenomena are relevant in the
context of self-healing materials.
Biomechanical engineering is involved with creating and producing a
variety of products in everyday use, from environmentally safe
plastics to various foods, fabrics, and medicines. A combination of
engineering and biology, it is a fast-growing field with many new
and exciting opportunities in genetic engineering and
biotechnology. However, research surrounding biomechanical
applications is scattered and often restricted, leading to the need
for a comprehensive publication of the recent advances and
developments in this emerging field. Design, Development, and
Optimization of Bio-Mechatronic Engineering Products provides
pivotal research on the application of combining mechanical
engineering with human biological systems in order to develop
bio-mechatronic products like pacemakers, artificial kidney
replacements, artificial hearts, and new joints or limbs to better
and more accurately monitor and advance human health. While
highlighting topics such as orthotic devices, inter-electrode gap,
and biomaterial applications, this publication explores producing
artificial material to work in sync with the human body. This book
is ideally designed for engineers, health professionals, technology
developers, researchers, academicians, and students.

control and computer engineering - Mechatronics - lies at the heart
of the innumerable gadgets, processes and technology without which
modern life would seem impossible. From auto-focus cameras to car
engine management systems, and from state-of-the-art robots to the
humble washing machine, Mechatronics has a hand in them all.
This book describes efficient and safe repair operations for
pipelines, and develops new methods for the detection and repair of
volumetric surface defects in transmission pipelines. It also
addresses the physics, mechanics, and applications of advanced
materials used for composite repair of corroded pipelines.
Presenting results obtained in the European Commission's INNOPIPES
FRAMEWORK 7 programme, it develops long-range ultrasonic and phased
array technologies for pipeline diagnostics, and explores their
interactions with discontinuities and directional properties of
ultrasonic antenna array. The book subsequently shares the results
of non-destructive testing for different types of materials
applications and advanced composite repair systems, and
characterizes the mechanical properties by means of fracture
methods and non-destructive techniques. In turn, the book assesses
the currently available technologies for reinforcement of
pipelines, drawing on the experience gai ned by project partners,
and evaluates the recovery of the carrying capacity of pipeline
sections with local corrosion damage by means of analytical and
numerical procedures. It develops an optimization method based on
the planning of experiments and surface techniques for advanced
composite repair systems, before validating the numerical models
developed and experimentally gauging the effectiveness of composite
repair with the help of full-scale hydraulic tests.

This application-oriented book introduces readers to the
associations and relationships between contact mechanics and
friction, providing them with a deeper understanding of tribology.
It addresses the related phenomena of contacts, adhesion, capillary
forces, friction, lubrication, and wear from a consistent point of
view. The author presents (1) methods for rough estimates of
tribological quantities, (2) simple and general methods for
analytical calculations, and (3) the crossover into numerical
simulation methods, the goal being to convey a consistent view of
tribological processes at various scales of magnitude (from
nanotribology to earthquake research). The book also explores the
system dynamic aspects of tribological systems, such as squeal and
its suppression, as well as other types of instabilities and
spatial patterns. It includes problems and worked-out solutions for
the respective chapters, giving readers ample opportunity to apply
the theory to practical situations and to deepen their
understanding of the material discussed. The second edition has
been extended with a more detailed exposition of elastohydrodynamic
lubrication, an updated chapter on numerical simulation methods in
contact mechanics, a new section on fretting in the chapter on
wear, as well as numerous new exercises and examples, which help to
make the book an excellent reference guide.
