“…However, it is believed that the strain induced in an artefact by a defined, reproducible loading condition is the most directly related to the structural integrity, because structural failure is a consequence of the strain induced by the loads in service. Therefore, the approach pioneered by, for example, Findeis et al, 21 Fruehmann et al 24 and Emery and Dulieu-Barton, 25 offer tremendous potential and should be combined with the quantitative comparison methodology based on image decomposition and a similarity measure, as for the validation process.…”

“…Recently, some investigators have examined the use in non-destructive evaluation of techniques employed routinely for quantitative stress analysis, such as electronic speckle pattern interferometry, 21,22 digital shearography 23 and thermoelastic stress analysis; 24,25 and, in the latter case, strain maps in the vicinity of the detected damage were generated, thus enabling direct assessment of the residual fatigue life. An implicit assumption in the use of this class of techniques is that damage which induces no discernible change in the strain distribution, when the component is subject to service loads, is of low interest because such damage has not degraded the performance of the component or structure, as demonstrated by the lack of change in the stress or strain distribution.…”

Experimental strain analysis, structural health monitoring and non-destructive testing and evaluation are regarded as separate disciplines that, in general, are deployed independently at different phases in the life cycle of an engineering component, i.e. in the design process, in service and after an event or service period, respectively. It is proposed that the integrated use of these three disciplines is advantageous and beneficial in terms of reduced capital and operational costs for critical and safety-relevant components, as well as, in validating simulations, in both quantifying and reducing risk of unexpected failure, and in estimating remanent life. We propose the foundation of this integration to be data-rich strain fields measured and compared quantitatively, with each other and with data from simulations, at temporal intervals during the life of a component.

Damages are inevitable in structures and effective damage detection techniques are important for maintaining their health. Many weight-sensitive engineering applications use composite materials, especially fiber-reinforced laminates. Common damages of these materials include delamination, fiber breakage, fiber pull-out, etc. Various non-destructive testing (NDT) techniques are reported in the literature for damage detection in composites, such as ultrasonic testing, vibration-based techniques, acoustic emission technique, optical NDT and imagining techniques. However, due to the complex properties of composite materials, conventional techniques for analyzing NDT data are difficult to implement. In this context, artificial neural network (ANN) technique is a promising alternative for analyzing NDT data for damage detection. In this study, an attempt is made to explore the state-of-the-art of damage detection in composites using NDT aided by ANN. The work discusses the pros and cons of different methods and is expected to help in identifying the appropriate method for damage detection in composites.

Diagnosis and prognosis of failures for aircrafts’ integrity are some of the most important regular functionalities in complex and safety-critical aircraft structures. Further, development of failure diagnostic tools such as Non-Destructive Testing (NDT) techniques, in particular, for aircraft composite materials, has been seen as a subject of intensive research over the last decades. The need for diagnostic and prognostic tools for composite materials in aircraft applications rises and draws increasing attention. Yet, there is still an ongoing need for developing new failure diagnostic tools to respond to the rapid industrial development and complex machine design. Such tools will ease the early detection and isolation of developing defects and the prediction of damages propagation; thus allowing for early implementation of preventive maintenance and serve as a countermeasure to the potential of catastrophic failure. In this paper, following a short introductory summary and definitions, this paper provides a brief literature review of recent research on failure diagnosis of composite materials with an emphasis on the use of NDT techniques in aerospace industry. In addition to this, within a some of significant NDT application extents, prognosis of composites is also briefly discussed.
