This new book on the fracture mechanics of concrete focuses on the
latest developments in computational theories, and how to apply
those theories to solve real engineering problems. Zihai Shi uses
his extensive research experience to present detailed examination
of multiple-crack analysis and mixed-mode fracture.
Compared with other mature engineering disciplines, fracture
mechanics of concrete is still a developing field with extensive
new research and development. In recent years many different models
and applications have been proposed for crack analysis; the author
assesses these in turn, identifying their limitations and offering
a detailed treatment of those which have been proved to be robust
by comprehensive use.
After introducing stress singularity in numerical modelling and
some basic modelling techniques, the Extended Fictitious Crack
Model (EFCM) for multiple-crack analysis is explained with
numerical application examples. This theoretical model is then
applied to study two important issues in fracture mechanics - crack
interaction and localization, and fracture modes and maximum loads.
The EFCM is then reformulated to include the shear transfer
mechanism on crack surfaces and the method is used to study
experimental problems.
With a carefully balanced mixture of theory, experiment and
application, Crack Analysis in Structural Concrete is an important
contribution to this fast-developing field of structural analysis
in concrete.
* Latest theoretical models analysed and tested
* Detailed assessment of multiple crack analysis and multi-mode
fractures
* Applications designed for solving real-life engineering problems
The effect of manmade activities is primarily local but can extend
far away from the location of intervention. This underlines the
importance of establishing coastal zone management plans covering
large stretches of coastlines.
In recent years, interest in Low Crested Structures (coastal
defense structures with a low-crest) has been growing together with
awareness of the sensitivity to environmental impacts produced by
coastal defenses.
The relation between wave climate, beach erosion, beach defence
means, habitat changes and beach value, which clearly exists based
on EC research results, suggests the necessity of an integrated
approach when designing coastal protection schemes. In accordance
with this need, the present design guidelines cover structure
stability and construction problems, hydro and morphodynamic
effects, environmental effects (colonisation of the structure and
water quality), societal and economic impacts (recreational
benefits, swimming safety, beach quality).
Environmental Design Guidelines for Low Crested Coastal Structures
is specifically dedicated to Low Crested Structures, and provides
methodological tools both for the engineering design of structures
and for the prediction of performance and environmental impacts of
such structures. A briefing of current best practice for local and
national planning authorities, statutory agencies and other
stakeholders in the coastal zone is also covered.
Presented in a generic way, this book is appropriate throughout the
European Union, taking into account current European Commission
policy and directives for the promotion of sustainable development
and integrated coastal zone management.
* Fills the gap between engineering and ecology in coastal defense
planning
* Shows the reader how to perform an integrated design of coastal
defense schemes
* Presents latest insights on hydro-morphodynamics induced by
structures
* Provides directly applicable tools for the design of low crested
structures
* Highlights socio-economic perspectives in coastal defense design
Climate for the 21st century is expected to be considerably
different from the present and recent past. Industrialization
growth combined with the increasing CO2 concentration in the
atmosphere and massive deforestation are well above the values over
the past several decades and are expected to further grow. Air
temperature is rising rapidly well as does the weather variability
producing frequent extreme events. Six of the ten warmest years
occurred in the 1990s. Temperatures predicted for the 21st century
ranges well above the present day value.
The time period of the last 100-200 years covered by the direct
meteorological observations is too short and does not provide
material to reliably assess what may happen over the next
hundred(s) years. A faithful prediction of the future requires
understanding how climate system works, i.e. to reconstruct past
climate much further in the past. Borehole paleoclimatology enables
climate reconstruction of the past several millennia, unlike proxy
methods provides direct past temperature assessment and can well
broaden the areal range to the remote regions poorly covered with
meteorological observations. Considerable debates have recently
focused on the causes of the present-day warming, i.e. to
distinguish between the natural and anthropogenic contribution to
the observed temperature increase, eventually to quantify their
regional distribution. Complex interpretation of borehole data with
the proxies and additional socio-economic information can hopefully
help. On observed data taken in various places all over the world
we demonstrate suitable examples of the interaction between the
subsurface temperature response to time changes in vegetation
cover, land-use (farming) and urbanization. Precise
temperature-time monitoring in shallow subsurface can further
provide the magnitude of the present-day warming within relatively
short time intervals.
As far as we know, there exists so far no book dealing entirely
with the subject of the Borehole climatology. Only relatively
rarely this method is mentioned in otherwise plentiful literature
on climate reconstruction or on climate modelling. There are,
however, series of papers focussing on various borehole--climate
related studies in numerous journals (e.g. Global and Planetary
Change, Climate Change, Tectonophysics, Journal of Geophysical
Research, Geophysical Research Letters, etc). Time to time a
special issue appears to summarize papers on this topic presented
during specialized symposia.

This book presents some fundamental concepts behind the basic
theories and tools of discrete element methods (DEM), its
historical development, and its wide scope of applications in
geology, geophysics and rock engineering. Unlike almost all books
available on the general subject of DEM, this book includes
coverage of both explicit and implicit DEM approaches, namely the
Distinct Element Methods and Discontinuous Deformation Analysis
(DDA) for both rigid and deformable blocks and particle systems,
and also the Discrete Fracture Network (DFN) approach for fluid
flow and solute transport simulations. The latter is actually also
a discrete approach of importance for rock mechanics and rock
engineering. In addition, brief introductions to some alternative
approaches are also provided, such as percolation theory and
Cosserat micromechanics equivalence to particle systems, which
often appear hand-in-hand with the DEM in the literature.
Fundamentals of the particle mechanics approach using DEM for
granular media is also presented.
- Presents the fundamental concepts of the discrete models for
fractured rocks, including constitutive models of rock fractures
and rock masses for stress, deformation and fluid flow
- Provides a comprehensive presentation on discrete element
methods, including distinct elements, discontinuous deformation
analysis, discrete fracture networks, particle mechanics and
Cosserat representation of granular media
- Features constitutive models of rock fractures and fracture
system characterization methods detaiing their significant impacts
on the performance and uncertainty of the DEM models

Industrial and domestic piping is increasingly made from various
plastics and composites, and these materials withstand heavy use
over long periods. They are, however, affected by environmental and
other factors over time and can degrade, causing major problems
within piping systems. Farshad's book deals with why plastic pipes
and systems fail, and with how to investigate and diagnose such
failures. Pipes may buckle, fracture, change in dimensions and
colour, blister and delaminate, corrode through stress, be abraded
and obstructed: all these cause problems and lead to loss of
efficient operation of a system. The author's experience is backed
up by a large data-base of results
* Wide target audience
* The only book covering the whole subject
* Unique approach based on long experience
Over recent years there have been substantial changes in those
industries which are concerned with the design, purchase and use of
special purpose (ie critical, high-revenue) rotating equipment. Key
personnel have been the victims of early retirement or have moved
to other industries: contractors and end-users have reduced their
technical staff and consequently have to learn complex material
'from scratch'. As a result, many companies are finding that they
are devoting unnecessary man hours to the discovery and explanation
of basic principles, and having to explain these to clients who
should already be aware of them. In addition, the lack of
understanding by contractors and users of equipment characteristics
and operating systems often results in a 'wrong fit' and a costly
reliability problem.
Forsthoffer's Rotating Equipment Handbooks: Auxiliary Systems deals
with types, function and application of each major system type,
(lubrication, control, liquid and gas seal, cooling, buffer gas and
pump flush) component selection and design of reservoirs, pump
systems, control valves and instrumentation, coolers/filters and
transfer valves, design audits and troubleshooting of systems and
components, maintenance, key reliability indicators, system
condition monitoring and much more.

The use of lasers which emit infra-red radiation and sophisticated
detectors of IR radiation is increasing dramatically: they are
being used for long-distance fibre-optic communications and remote
environmental monitoring and sensing. Thus they are of interest to
the telecommunications industry and the military in particular.
This book has been designed to bring together what is known on
these devices, using an international group of contributors.
The idea for this book came out of the EURESCO Conference on High
Performance Fibers: Euroconference on Fiber Fracture in 2000. Many
of the books that are currently available look at different aspects
of fiber processing, properties, or applications, but none are
focussed on the fracture behaviour of fibers. This book presents
the mechancisms and models of fiber fracture currently available
for both natural and synthetic fibers, and it is expected that
increasingly there will be cross fertilization between the fields,
opening new frontiers in academic research and more competitive
products for industry. It covers the following areas of fiber
fracture: ceramic fibers; glass fibers; carbon filters; metallic
fibers and thin wires; polymeric fibers; and carbon nanotubes.
The objective of the 28th Leeds-Lyon Symposium on Tribology was to
define current understanding of the science relating to boundary
and mixed lubrication and to compare this with the needs of
industry in terms of applications.
Major advances have been made in recent years in areas such as
contact mechanics, wear, elastohydrodynamic lubrication
incorporating surface texture, lubricant interactions with surfaces
and the experimental interrogation of surface topography, surface
films and lubricant film thickness. However, the needs of industry
are equally intense with a seemingly relentless drive towards more
compact, efficient and durable tribological systems.
"Boundary and Mixed Lubrication: Science and Applications"
publishes peer-reviewed papers presented at the 28th Leeds-Lyon
Symposium on Tribology. The Keynote address was presented by
Professor Koji Kato, Tohoku University, Sendai, Japan under the
title "Wear of Boundary or Mixed Lubrication Regimes," which set
the scene for the meeting with a review of recent scientific
developments with a clear focus on the potential for technological
and industrial development.
Engineering rock mechanics is the discipline used to design
structures built in rock. These structures encompass building
foundations, dams, slopes, shafts, tunnels, caverns, hydroelectric
schemes, mines, radioactive waste repositories and geothermal
energy projects: in short, any structure built on or in a rock
mass. Despite the variety of projects that use rock engineering,
the principles remain the same. Engineering Rock Mechanics clearly
and systematically explains the key principles behind rock
engineering.
The book covers the basic rock mechanics principles; how to study
the interactions between these principles and a discussion on the
fundamentals of excavation and support and the application of these
in the design of surface and underground structures. Engineering
Rock Mechanics is recommended as an across-the-board source of
information for the benefit of anyone involved in rock mechanics
and rock engineering.
This fully illustrated text explains the basic measurement
techniques, describes the commercially available instruments and
provides an overview of the current perception of 3-D topography
analysis in the academic world and industry, and the commonly used
3-D parameters and plots for the characterizing and visualizing 3-D
surface topography.
It also includes new sections providing full treatment of surface
characterization, filtering technology and engineered surfaces, as
well as a fully updated bibliography.
Recent years have brought substantial developments in electrical
drive technology, with the appearance of highly rated,
very-high-speed power-electronic switches, combined with
microcomputer control systems.
This popular textbook has been thoroughly revised and updated in
the light of these changes. It retains its successful formula of
teaching through worked examples, which are put in context with
concise explanations of theory, revision of equations and
discussion of the engineering implications. Numerous problems are
also provided, with answers supplied.
The third edition includes enhanced coverage of power-electronic
systems and new material on closed-loop control, in addition to
thorough treatment of electrical machines.
