Book Description
Non-destructive Testing of Impact Damage in Fiber-reinforced Polymer Composites: Fundamentals and Applications provides detailed knowledge on the fundamentals and applications of frequently used nondestructive testing (NDT) techniques utilized to assess impact damage in composite structures. This book starts with an introduction to impact damage in composite structures, each subsequent chapter focuses on evaluating damage using specific NDT methods. Chapters 2–4 concentrate on vision-based NDT methods such as visual inspection, digital image correlation, and digital shearography. Following this, Chapters 5–6 delve into ultrasound-based methods, including acoustic emission and phased-array ultrasonic inspection. Radiation-based methods, micro-CT, and thermography are discussed in Chapters 7 and 8, while Chapters 9 and 10 elucidate microwave inspection and electrical impedance tomography. This book is a useful reference for both academia and industry and covers the fundamentals, practical tips, case studies, and applications, as well as current research trends and future possibilities, for each technique. Insights into the diverse damage levels in composite materials resulting from low-velocity impact, ranging from micro matrix cracks to severe delamination and fiber breakage Covers a broad range of NDT techniques, including recently developed NDT techniques, suitable for detecting impact damage in composite materials Serves as a valuable reference for both academia and industry, providing comprehensive coverage of fundamental principles, practical insights, applications, case studies, current research trends, and future prospects for each NDT technique

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
The primary objective of this study was to investigate the abilities of acoustic emission testing and self-sensing fibres to detect damage in composite materials. This was achieved by performing acoustic emission testing on fibre samples and resin samples during tensile tests. In parallel to the acoustic emission testing the changes in strain for the resin samples was recorded using electrical resistance strain gauges and fibre Bragg gratings. Acoustic emission testing of Self-sensing fibre composites allowed the recorded changes in the light intensity transmitted by the fibres to be analysed in conjunction with the acoustic emission data. The fabrication of the three different sample types is presented as is the installation of the electrical resistance strain gauges and fibre Bragg gratings. The experimental procedure and method of data capture is detailed for tensile and acoustic emission testing, strain data and Self-sensing fibre data. The fabrication and testing of the samples was performed successfully. The testing procedure and analysis of results demonstrates the accurate use of acoustic emission and the potential of self-sensing fibres in detecting damage in composite materials.
