This contributed volume is designed for fundamental understanding of fracture behavior of composites applied in core industrial sectors such as mechanical, electronics, Automotive, civil structures, and aerospace research and fills the gap of knowledge on fracture analysis. The book is primarily written for senior undergraduates, graduate students, and academic researchers in above mentioned fields. Presents crack growth, RU life in structures and ensures laminate integrity; Explains NDT in composites, AI for RUL & fatigue life, and repair for extended life; Discusses Temporal Dependency Analysis in Predicting RUL of Aircraft Structures and study Aerospace-Grade Fiber/Epoxy.
