Book Description
In this book, two kinds of analysis based on acoustic emission recorded during mechanical tests are investigated. In the first, individual, analysis, acoustic signature of each damage mechanism is characterized. So with a clustering method, AE signals that have similar shapes or similar features can be group together into a cluster. Afterwards, each cluster can be linked with a main damage. The second analysis is based on a global AE analysis, on the investigation of liberated energy, with a view to identify a critical point. So beyond this characteristic point, the criticality can be modeled with a power-law in order to evaluate time to failure.

Book Description
A review of the application of acoustic emission analysis to the evaluation of material properties and defect structure is presented, including a brief discussion of experimental techniques. Sources of acoustic emission in composite materials under strain are discussed. Particular attention is directed toward fiber reinforced composites, and experimental results on filament wound NOL rings and vessels (glass/epoxy) are reported. It is concluded that acoustic emission data are helpful in establishing the mechanisms governing operative fracture modes and assessing structural integrity.

Book Description
Presents the latest strategies in the development and use of composite materials for large structures and the effects of defects Practical Design and Validation of Composites Structures: Effects of Defects offers an important guide to the use of fiber-reinforced composites and how they affect the durability and safety of engineering structures such as aircraft, ships, bridges, wind turbines as well as sporting equipment. The text draws on the authors’ direct experience in industry and academia to cover the most recent strategies in the development of composite structures and uniquely integrates the assessment of the effects of defects introduced during production. This comprehensive resource builds on an essential introduction to the characteristics of composites and the most common types of defects encountered in production. The authors review the recent manufacturing methods and technologies used for inspecting composite structures and the design issues related to an analysis of their failure and strength incorporating the variability of processing. The text also contains information on the latest regulatory requirements and the relevant standards associated with the testing and design within a robust design philosophy and approach. This important resource: Offers a comprehensive review of the most current regulatory developments in the use of composites for the construction of complex composite structures Presents information on the basic characteristics of composites Includes testing strategies for determining the impacts of production defects Reviews the most current manufacturing methods and inspection technologies in the field Contains methods for statistical analysis and processing of experimental effects of defects test data Written for professional engineers in mechanical engineering, automotive engineering, aerospace engineering, civil engineering, and energy engineering as well as industry and academic researchers, Practical Design and Validation of Composites Structures: Effects of Defects is the hands-on text that covers the essential information needed to understand the use of composites and how they affect complex engineering projects using composites.
