Preface

Fracture mechanics deals with the cracking behavior of materials, and cracking defines the limit state for many components of engineering systems. Therefore, fracture mechanics is a field that provides useful tools for many engineering practitioners and designers from various disciplines. It is a relatively new branch of mechanics and more advanced in theoretical basis rather than practical

applications. However, due to its useful approach in handling failure of materials,

ensuring safer airplanes, space shuttles, ships, cranes, buildings, bridges and other mechanical systems for use in medicine, for example, destroying arterial plaques or kidney stones. In short, application of fracture mechanics has potential to give us tools in solution of many design and analysis problems. In this context, this book introduces and supports the understanding of fracture mechanics principles to enhance the knowledge and application of specialists in all related areas of

*Fracture Mechanics Applications* contains eight chapters written by researchers and experts in the field. It is designed for graduate students, researchers, and practicing

We would like to express our deepest appreciation to academicians, scientists, and our colleagues and friends globally who have significantly contributed in the broad field of fracture mechanics, and especially to the authors of the chapters in this book. We are also grateful to IntechOpen for publishing the book, which we hope to

Chapter 1 introduces rupture theory of soft-matter quasicrystals. Chapters 2 provides insight into application of the J-integral for the fracture assessment of welded polymeric components. Chapter 3 describes fatigue limit reliability analysis for notched material with some kinds of dense inhomogeneities using fracture mechanics. Chapter 4 deals with the fracture behavior of pure and hybrid intraply knitted fabric-reinforced polymer composites. Chapter 5 explains the construction of an artificial neural network to detect structural damage. Chapter 6 introduces the mechanism of misalignment of saw cutting cracks in concrete pavement. Chapter 7 presents the effect of geometrical factors on the surface pressure distribution on a human phantom model following shock exposure. Finally, Chapter 8 discusses blast
