Fatigue and Fracture of Adhesively-Bonded Composite Joints


Book Description

It is commonly accepted that the majority of engineering failures happen due to fatigue or fracture phenomena. Adhesive bonding is a prevailing joining technique, widely used for critical connections in composite structures. However, the lack of knowledge regarding fatigue and fracture behaviour, and the shortage of tools for credible fatigue design, hinders the potential benefits of adhesively bonded joints. The demand for reliable and safe structures necessitates deep knowledge in this area in order to avoid catastrophic structural failures. This book reviews recent research in the field of fatigue and fracture of adhesively-bonded composite joints. The first part of the book discusses the experimental investigation of the reliability of adhesively-bonded composite joints, current research on understanding damage mechanisms, fatigue and fracture, durability and ageing as well as implications for design. The second part of the book covers the modelling of bond performance and failure mechanisms in different loading conditions. - A detailed reference work for researchers in aerospace and engineering - Expert coverage of different adhesively bonded composite joint structures - An overview of joint failure




Strength Prediction of Adhesively-Bonded Joints


Book Description

Adhesively-bonded joints provide many advantages over conventional mechanical fasteners and are increasingly receiving attention as an alternative to mechanical joints in engineering applications. The traditional fasteners usually result in the cutting of fibers and hence the introduction of stress concentrations, both of which reduce structural integrity. By contrast, bonded joints are more continuous and have potential advantages of strength-to-weight ratio, design flexibility, and ease of fabrication. This book provides an overview of available analytical methods as well as numerical methods.




Adhesive Joints: Formation, Characteristics and Testing


Book Description

This volume documents the proceedings of the Second International Symposium on Adhesive Joints: Formation, Characteristics and Testing held in Newark, NJ, May 22-24, 2000. Since the first symposium, held in 1982, there had been tremendous research activity dealing with many aspects of adhesive joints. This volume contains a total of 21 papers, which were all properly peer reviewed, revised and edited before inclusion. Therefore, this book is not merely a collection of unreviewed manuscripts, but rather represents information which has passed peer scrutiny. Furthermore, the authors were asked to update their manuscripts, so the information contained in this book should be current and fresh. The book is divided into three parts: 1) General Papers; 2) Evaluation, Analysis and Testing; and 3) Durability Aspects. The topics covered include: molecular brush concepts in enhancing strength of adhesive joints; factors affecting performance of adhesive joints; substrate preparation and modification; interfacial/interphasial aspects; determination of locus of failure; analysis and evaluation of adhesive joints using various techniques; testing of adhesive joints; stress analysis; application of fracture mechanics; durability aspects; accelerated environmental degradation of adhesive joints; solvent uptake; and adhesives with special characteristics. This volume represents a commentary on the current R&D activity in this arena and it should be of great value and interest to anyone interested in adhesive bonding / adhesive joints. Furthermore, this volume contains a number of excellent review/overview articles, which should be of particular value.




Structural Adhesive Joints in Engineering


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.
