Preface

Engineering material science is a diverse field that can be presented in many different ways. The title of this book, *Engineering failure analysis*, reflects the attitude of the present treatment. The book is about theory and practical applications, but the main focus is on theory with direct consequences for the understanding and practical use of available techniques. This book gives the reader an insight on basic principles to allow them to approach a practical problem.

The core material of the book should be suitable for a graduate-level course in engineering materials, in particular engineering failure analysis. As a prerequisite for such a course, it is expected, although not absolutely necessary, to require that the student should be familiar with basic mechanical properties of materials.

The structure of this book is as follows; initially, basic theories and definitions to failure modes, analysis and case studies are presented. This is followed by the topics addressed by the key chapters including: information on stress analysis – strengths and limitations of traditional theoretical approaches to FRP laminate design against failure; stress corrosion cracking behaviour of materials; failure analysis and durability issues. For example, one chapter describes fracture behaviour of solid-state welded joints in detail. The chapter presents a detailed analysis of practical and theoretical studies, also a methodology for characterising fracture behaviour of solid-state welded joints. Another chapter, *An effective approach to investigate turbine hot component failure,* investigates the influence of key factors such as variable fluid dynamics, turbine effect, nozzle guide vane, air cooling, and failure in such a system. The book contains a wide range of key topics within the field of engineering materials.

Finally, editing a book takes time, and I probably would not have been able to finish this one on time had I not had the privilege of allocated research activities time and I thank Ewen Constant, Head of Department of Aeronautical and Mechanical Engineering and Dr. Paul Davies, Head of School of Engineering for making this possible and providing inspiring working conditions. Support from Mateo Pulko, Author Service Manager, IntechOpen for coordinating and completing the book has also been important.

It was unavoidable that a lot of the editing of the book had to be done on overtime. I thank my family for letting me use their time.
