Preface

Materials science is used to design and discover new materials for use in buildings, offices, cars, aircrafts, ships, rockets, and much more. Over the years, I have worked in all aspects of materials engineering, including development, alloying, casting, mechanical testing, and characterisation. I have always wanted to put my efforts into action by gathering researchers from around the world to contribute to the field and support other researchers to develop materials for various applications. This book is a result of those efforts. Over the years, various models have been proposed and utilised to predict the performance of materials under fatigue conditions. Some of these models proved to be accurate, whereas others failed to predict fatigue behaviour. The strength of any predictive tool depends on the employment of physically meaningful parameters that replicate real-life conditions. This book discusses fatigue testing and modelling in both metallic and non-metallic materials. It also presents predictive models and finite element (FE) activities to illustrate the behaviour of materials in real-life conditions. I am grateful to all the authors for their valuable efforts and contributions. I am also grateful to IntechOpen for publishing this important work.
