This book provides a state-of-the-art review of the fail-safe and damage tolerance approaches, allowing weight savings and increasing aircraft reliability and structural integrity.

The application of the damage tolerance approach requires extensive know-how of the fatigue and fracture properties, corrosion strength, potential failure modes and non-destructive inspection techniques, particularly minimum detectable defect and inspection intervals. In parallel, engineering practice involving damage tolerance requires numerical techniques for stress analysis of cracked structures. These evolved from basic mode I evaluations using rough finite element approaches, to current 3D modeling based on energetic approaches as the VCCT, or simulation of joining processes. This book provides a concise introduction to this subject.

Autorentext

Sergio Tavares got his doctorate at the Universidade do Porto in 2011, in the frame of the MIT-Portugal programme; his thesis and subsequent R&D work concern integral structures. Paulo de Castro got his PhD at Cranfield Institute of Technology in 1980, and has since worked in fracture and fatigue problems, through a variety of R&D projects as EU SMAAC, ADMIRE and DATON, Al-Li work for ESA, among others.
