Book Description
The possible use of adhesives in a new design should always be considered because of the economic and technical benefits thatthey can confer. Light, stiff and economic structures, free of the blemishes caused by conventional assembly methods, can be fabricated from a variety of materials in combinations which would otherwise be hard to achieve. Similarly, mechanisms may be built up using bonding techniques which are free of the costs and stresses implicit in press fitting. Adhesives are not a panacea, but they do have a great deal to offer as is shown by the vital role they play in modern production engineering. Yet, despite this, they are not generally regarded with enthusiasm by engineers and designers. The reason for this is not hard to find. There are so many adhesives with such diverse properties that, in the absence of a unifying science which can explain not only why adhesives stick but why they behave as they do, a very strong incentive is required to guarantee perseverance. In addition, although the polymeric structures of adhesives are well understood, this knowledge is usually of little help to the engineer who is used to dealing in precise terms and may be readily put off by a subject which he tends to regard as being arcane and wooly.

Book Description
The intention of this book is that it should contain everything an engineer needs to know to be able to design and produce adhesively bonded joints which are required to carry significant loads. The advan tages and disadvantages of bonding are given, together with a sufficient understanding of the necessary mechanics and chemistry to enable the designer to make a sound engineering judgement in any particular case. The stresses in joints are discussed extensively so that the engineer can get sufficient philosophy or feel for them, or can delve more deeply into the mathematics to obtain quantitative solutions even with elasto plastic behaviour. A critical description is given of standard methods of testing adhesives, both destructively and non-destructively. The essen tial chemistry of adhesives and the importance of surface preparation are described and guidance is given for adhesive selection by me ans of check lists. For many applications, there will not be a unique adhesive which alone is suitable, and factors such as cost, convenience, produc tion considerations or familiarity may be decisive. A list of applications is given as examples. The authors wish to increase the confidence of engineers using adhesive bonding in load-bearing applications by the information and experience presented. With increasing experience of adhesives en gineering, design will become more elegant as weH as more fitted to its products.

Book Description
The Mechanics of Adhesion shows that adhesion science and technology is inherently an interdisciplinary field, requiring fundamental understanding of mechanics, surfaces, and materials. This volume comprises 19 chapters. Starting with a background and introduction to stress transfer principles; fracture mechanics and singularities; and an energy approach to debonding, the volume continues with analysis of structural lap and butt joint configurations. It then continues with discussions of test methods for strength and constitutive properties; fracture; peel; coatings, the case of adhesion to a single substrate; elastomeric adhesives such as sealants. The role of mechanics in determining the locus of failure in bonded joints is discussed, followed by a chapter on rheology relevant to adhesives and sealants. Pressure sensitive adhesive performance; the principles of tack and tack measurements; and contact mechanics relevant to wetting and surface energy measurements are then covered. The volume concludes with sections on fibermatrix bonding and reinforcement; durability considerations for adhesive bonds; ultrasonic non-destructive evaluation of adhesive bonds; and design of adhesive bonds from a strength perspective. This book will be of interest to practitioners in the fields of engineering and to those with an interest in adhesion science.

Book Description
Insufficient knowledge, time limitations, and budget constraints often result in poor material selection and implementation, which can lead to uncertain performance and premature failure of mechanical and electro-mechanical products. Selection of Engineering Materials and Adhesives is a professional guide to choosing the most appropriate materials and adhesives for product development applications from the onset. This text emphasizes material properties and classifications, fabrication and processing considerations, performance objectives, and selection based on specific application requirements, such as frequency of use (duty cycle) and operating environment. Each chapter focuses on a particular material family, covering ferrous and non-ferrous metals, including steels, cast-iron, aluminum, and titanium, as well as plastics such as PVC, acrylics, and nylons. Unique to this book on material selection, the final chapter discusses critical aspects of adhesives, including cure methods and joint configurations. Selection of Engineering Materials and Adhesives presents materials that are most often used for selection processes and applications in product development. This book is an ideal text for senior level undergraduate or graduate courses in mechanical engineering and materials science as well as recent graduates or managers who are tasked with the daunting job of selecting a material for a new application or justifying a long-used material in a specific application. It embodies the author's own experience and lectures on this subject, taught at UCLA Extension, and provides students as well as practicing engineers the tools to systematically select the most appropriate materials and adhesives for their design work.

Book Description
Over the last decade, or so, the growth in the use of adhesives, especially in ever more technically demanding applications, has been rapid and many major developments in the technology of adhesives have been reported. This growth has also led to attention being focused on somewhat more basic studies of the science of adhesion and adhesives, and in recent years our level of fundamental knowledge concerning the formation and mechanical performance of adhesive joints has increased dramatically. Such studies have, of course, been aided greatly by the development of the tools at the disposal of the investigators. For example, specific surface analytical techniques, such as X-ray photoelectron and secondary-ion mass spectroscopy, and the increasingly sophisticated methods of stress analysis and fracture mechanics have been put to good use in furthering our understanding of the science of adhesion and adhesives. The present book attempts to review the multidisciplined subject of adhesion and adhesives, considering both the science and technology involved in the formation and mechanical performance of adhesive joints. The author would like to thank his friends and colleagues for useful discus sions and help in the preparation of this book. I am particularly grateful to P. Cawley, J. Comyn, W. A. Lees, A. C. Roulin-Moloney, W. C. Wake, J. G. Williams and R. J. Young who have read and commented on various chapters and P. Farr for preparing the diagrams.
