Volume is indexed by Thomson Reuters BCI (WoS).The aim of this book is to develop, in the reader, the necessary skills required for designing materials, components and structures so as to resist fracture and failure in engineering applications. In order to achieve this objective, the authors have adopted a combined materials science-fracture mechanics-design approach. Although the material covered is designed for an advanced undergraduate course in metallurgy/materials engineering, students coming from mechanical, civil or aerospace engineering backgrounds will also be able to use this text as a course/reference book. In addition to students, practising engineers and production mangers will also find this book very useful; particular with regard to designing components and machine elements so as to resist fracture and failure in critical applications.
