Metal Failures gives engineers the intellectual tools and practical understanding needed to analyze failures from a structural point of view. Its proven methods of examination and analysis enable investigators to:
* Reach correct, fact-based conclusions on the causes of metal failures
* Present and defend these conclusions before highly critical bodies
* Suggest design improvements that may prevent future failures
Analytical methods presented include stress analysis, fracture mechanics, fatigue analysis, corrosion science, and nondestructive testing. Numerous case studies illustrate the application of basic principles of metallurgy and failure analysis to a wide variety of real-world situations. Readers learn how to investigate and analyze failures that involve:
* Alloys and coatings
* Brittle and ductile fractures
* Thermal and residual stresses
* Creep and fatigue
* Corrosion, hydrogen embrittlement, and stress-corrosion cracking
This useful professional reference is also an excellent learning tool for senior-level students in mechanical, materials, and civil engineering.
Summary: Dr. Michael Stevenson
Rating: 5
This text provides perhaps the most concise and authoritative resource for the field of Metallurgical Failure Analysis that I have read. Rather than apporaching failures from a cookbook perspective, that is only linking cause to failure through single case histories, this author presents the fundamental concepts of the discipline and suplements them with appropriate examples.After reading the book, I am considering using it a text to a course that previously could only be approached with personal course notes. This is the most comprehensive and fundamentally organized book I have read in years. Well worth twice the price.

From Charpy to Present Impact Testing contains 52 peer-reviewed papers selected from those presented at the Charpy Centenary Conference held in Poitiers, France, 2-5 October 2001.
The name of Charpy remains associated with impact testing on notched specimens. At a time when many steam engines exploded, engineers were preoccupied with studying the resistance of steels to impact loading.
The Charpy test has provided invaluable indications on the impact properties of materials. It revealed the brittle ductile transition of ferritic steels.
The Charpy test is able to provide more quantitative results by instrumenting the striker, which allows the evolution of the applied load during the impact to be determined. The Charpy test is of great importance to evaluate the embrittlement of steels by irradiation in nuclear reactors. Progress in computer programming has allowed for a computer model of the test to be developed; a difficult task in view of its dynamic, three dimensional, adiabatic nature. Together with precise observations of the processes of fracture, this opens the possibility of transferring quantitatively the results of Charpy tests to real components. This test has also been extended to materials other than steels, and is also frequently used to test polymeric materials.
Thus the Charpy test is a tool of great importance and is still at the root of a number of investigations; this is the reason why it was felt that the centenary of the Charpy test had to be celebrated. The Socit Fran§aise de Mtallurgie et de Matriaux decided to organise an international conference which was put under the auspices of the European Society for the Integrity of Structures (ESIS).
This Charpy Centenary Conference (CCC 2001) was held in Poitiers, at Futuroscope in October 2001. More than 150 participants from 17 countries took part in the discussions and about one hundred presentations were given. An exhibition of equipment showed, not only present day testing machines, but also one of the first Charpy pendulums, brought all the way from Imperial College in London.
From Charpy to Present Impact Testing puts together a number of significant contributions. They are classified into 6 headings:

This book is an overview of ESIS Technical Committee 4's activities since the mid-1980s. A wide range of tests is described and the numerous authors is a reflection of the wide and enthusiastic support we have had.
With the establishment of the Technical Committee 4, two major areas were identified as appropriate for the activity. Firstly there was an urgent need for standard, fracture mechanics based, test methods to be designed for polymers and composites. A good deal of academic work had been done, but the usefulness to industry was limited by the lack of agreed standards. Secondly there was a perceived need to explore the use of such data in the design of plastic parts. Some modest efforts were made in early meetings to explore this, but little progress was made. In contrast things moved along briskly in the standards work and this has dominated the activity for the last fourteen years. The design issue remains a future goal.

Product Description:
Modifiers have been used to improve the performance of asphalt/aggregate mixtures for building roads for over the past hundred years and during that time the industry has evolved into a sophisticated sector that is heavily regulated by national and European standards.
The modifiers used take many different forms: polymers, latex, and many chemical additives. Determining how modifiers actually affect the performance of a mixture and establishing construction quality control procedures for these modifiers can be extremely difficult. In the past these difficulties have caused many specifying agencies to avoid the use of mixture modifiers when they could be of benefit to the performance of the road.
This review explores the type of polymers used in asphalt, why they are used, where they are used in terms of applications and the benefits they offer to industry and the road user. In particular, the reader will understand how polymers can be used to enhance the functionality of asphalt, that is to overcome deterioration mechanisms by enhancing asphalt stiffnessorflexibility,orby making it more resistant to deformation (rutting) caused by traffic.
This review of polymers in asphalt is supported by an indexed section containing several hundred key references and abstracts selected from the Polymer Library. It is aimed at anyone who has an interest in polymers and their highway applications.

Product Description:
"The construction industry increasingly requires products that are cost effective and easy to use, to enable fast track application whilst achieving a high physical performance. Incorporating a polymer in a cementitious mix brings key advantages, particularly in terms of workability, abrasion and impact resistance, with the resulting physical and chemical properties dependent upon the nature of the polymer material and the quantity used in relation to the cement phase.
This Rapra Handbook is intended to provide an insight into the uses of polymers within the construction industry. It describes the conception of polymer-modified cementitious materials through to the array of polymer-basedorpolymer-modified material utilised in modern day construction.
It not only covers the use of polymers in direct combination with cement but polymer concrete, impregnation of polymers into the concrete substrate and other polymer-based products, (i.e., coatings and adhesives). Both natural and synthetic polymers are reviewed.
This book is aimed at all those who are working with cement, and also at anyone who needs more information about this most versatile of materials, offering insight into:
the common polymers used in cementitious materials polymer concrete polymer Portland cement concrete reinforcement using synthetic fibres adhesives and coatings "

Author: Richard A. Kuntze. | Size: 3.3 MB | Format:PDF | Publisher: ASTM International Publication | Year: 2009 | pages: 120 | ISBN: 978-0-8031-7015-5
The purpose of this manuscript is to close a perceived gap between the academic and applied aspects of gypsum science and technology since a textbook covering these subjects is not available. Moreover, academic publications seem to deal with relatively narrow subjects and are concerned with cataloguing research results with little applied interpretation. In contrast, the practical literature is dispersed over a wide range of sources and gives the distinct impression of being unfocused. It is hoped that closing this gap will help to solve problems or to clarify situations that technologists and engineers may encounter and that may not necessarily be well understood. Therefore, it is the intention to interpret the essential literature on gypsum and to place the information provided into its proper context. To achieve this, the characteristic properties of gypsum and cementitious materials derived from it have been discussed in terms of their strength and weaknesses, taking into consideration both historical and modern points of view. In any case, this manuscript is written in a manner which should make it acceptable and accessible not only to a specific audience but also to others generally interested in this subject.
An equally important reason for preparing this manuscript is the fact that misconceptions continue to resurface on key issues and these are unusually persistent. They touch on all categories from ancient history to modern properties such as dehydration, -hemihydrate formation, water demand, aging and disintegration, rehydration and setting, as well as physical characteristics such as strength and gypsum board nail pull resistance. This has been the case since the time of Lavoisier and Le Chatelier in the 18th and 19th century, who first dealt with the dehydration and rehydration of gypsum in a modern scientific manner. A contributing factor has been the recent replacement of scientific research with current issues. Process research has become a most diluted and misquoted phrase. To a degree, the decline of gypsum research reflects the shift from gypsum plaster applied in the field to the manufacture of gypsum board in plants.
