Book Description :

Structural health monitoring (SHM) is a relatively new and alternative way of non-destructive inspection (NDI). It is the process of implementing a damage detection and characterization strategy for composite structures. The basis of SHM is the application of permanent fixed sensors on a structure, combined with minimum manual intervention to monitor its structural integrity. These sensors detect changes to the material and/or geometric properties of a structural system, including changes to the boundary conditions and system connectivity, which adversely affect the system's performance. This book's primary focus is on the diagnostics element of SHM, namely damage detection in composite structures. The techniques covered include the use of Piezoelectric transducers for active and passive Ultrasonics guided waves and electromechanical impedance measurements, and fiber optic sensors for strain sensing. It also includes numerical modeling of wave propagation in composite structures. Contributed chapters written by leading researchers in the field describe each of these techniques, making it a key text for researchers and NDI practitioners as well as postgraduate students in a number of specialties including materials, aerospace, mechanical and computational engineering.

Book Description :

Report developed under STTR contract for Topic F045-016-0125 addresses dynamic-based damage identification techniques for structural health monitoring (SHM) of aerospace structures. Two systems (i.e., the scanning laser vibrometer (SLV) and PVDF sensor) are used to acquire the dynamic information, and effective damage detection algorithms (e.g., the gapped smoothing method (GSM) and generalized fractal dimension (GFD) and schemes (e.g., the uniform load surface (ULS) and combined static/dynamic techniques) are developed to evaluate the damage. It is demonstrated that both the GSM and GFD methods are capable of identifying damage without baseline information of healthy structure. Application of the static/dynamic approach improves the performance of the damage identification, and the ULS increases the effectiveness of the detection at low modes. In general, the PVDF sensor system is good for acquiring several low curvature mode shapes; while the SLV system can generate higher displacement modes. Utilizing the advantages of each measurement system, the proposed identification algorithms have great potential for viable SHM products, e.g., the PVDF sensor system for on-board and the SLV system for portable on-site monitoring. The proposed sensor systems and developed identification techniques pave the foundation for further refinement of the dynamics-based method, field implementation and commercial development.

Book Description :

This work consisted in the research and development of a phased array embedded system for Structural Health Monitoring (SHM) of aircraft structures. This system is based on piezoelectric (PZT) transducers to excite fast propagating first symmetric Lambwave mode (S0) wavefronts. The intent of this research is to contribute for an increasing safety and efficient operation of aircraft. Currently applied ultrasound inspections to aircraft structures in operation, as a conventional Non Destructive Tests and Evaluations (NDT & E) technique, were reviewed. Such and the previous development of a Lamb wave based SHM system using PZT transducers in a network configuration served as the basis and for comparison to the phased array SHM system developed. Lamb waves' propagation behaviour was carefully analyzed and a linear PZT phased array SHM system was developed and experimentally tested. The PZT phased array was applied to representative aircraft structural aluminum panels, considering also the existence of structural reinforcements and joints. New techniques, hardware and software, leading to automated damage detection and location, were researched, developed and implemented. Tests for damage detection and location were performed, with the introduction of damages into the specimens being simulated by surface and through the thickness holes and cuts. Damages with a maximum dimension of 1mm applied cumulatively to the specimens subject to different boundary conditions were successfully detected and located.

Book Description :

Structural health monitoring (SHM) uses one or more in situ sensing systems placed in or around a structure, providing real-time evaluation of its performance and ultimately preventing structural failure. Although most commonly used in civil engineering, such as in roads, bridges, and dams, SHM is now finding applications in other engineering environments, such as naval and aerospace engineering. Written by a highly respected expert in the field, Structural Sensing, Health Monitoring, and Performance Evaluation provides the first comprehensive coverage of SHM. The text begins with a review of the various types of sensors currently used in SHM, including point sensors and noncontact systems. Subsequent chapters explain the processing and interpretation of data from a number of sensors working in parallel. After considering issues related to the structures themselves, the author surveys the design of a tailor-made SHM system. He also presents a collection of case studies, many of which are drawn from his own experiences. Exploring the power of sensors, this book shows how SHM technologies can be applied to a variety of structures and systems, including multistory buildings, offshore wind energy plants, and ecological systems.

The book includes the research papers presented in the final conference of the EU funded SARISTU (Smart Intelligent Aircraft Structures) project, held at Moscow, Russia between 19-21 of May 2015. The SARISTU project, which was launched in September 2011, developed and tested a variety of individual applications as well as their combinations. With a strong focus on actual physical integration and subsequent material and structural testing, SARISTU has been responsible for important progress on the route to industrialization of structure integrated functionalities such as Conformal Morphing, Structural Health Monitoring and Nanocomposites. The gap- and edge-free deformation of aerodynamic surfaces known as conformal morphing has gained previously unrealized capabilities such as inherent de-icing, erosion protection and lightning strike protection, while at the same time the technological risk has been greatly reduced. Individual structural health monitoring techniques can now be applied at the part-manufacturing level rather than via extending an aircraft’s time in the final assembly line. And nanocomposites no longer lose their improved properties when trying to upscale from neat resin testing to full laminate testing at element level. As such, this book familiarizes the reader with the most significant develo pments, achievements and key technological steps which have been made possible through the four-year long cooperation of 64 leading entities from 16 different countries with the financial support of the European Commission.

Book Description :

Structural Health Monitoring and Integrity Management is a collection of the papers presented at the 2nd International Conference of Structural Health Monitoring and Integrity Management (ICSHMIM2014, Nanjing, China, 24-26 September 2014), and addresses the most recent developments in the field of Structural Health Monitoring (SHM) and integrity management from around the world. It is also generally acknowledged that a clear advantage of SHM-technology over traditional NDT methods is the closer interaction and automation of sensing, diagnostics, prognostics and condition-based maintenance that SHM enables. As SHM is a system-level approach which integrates sensors/actuators networks with structures, software to interpret sensor signals, and hardware to process and manage the signals, its maturity based on the complexity and targeted solutions can be classified into four different sequential levels: detection, identification, quantification, and decision. Detection is the lowest maturity level that the technology can achieve. Once detection is confirmed with a highdegree of confidence, identification of the occurrence of the event in time and space domain is critical, which then can potentially lead to the quantification of the event. A more accurate quantification may lead to a better decision, which provides a much more efficient management solution for the structures than traditional inspection techniques, leading to a system platform for autonomous or intelligent structures. Structural Health Monitoring and Integrity Management will be invaluable to academics and professionals interested in applications encompassing traditional aerospace structures and civil infrastructures, in special equipment and marine/offshore structures, as well as in a variety of other structures and platforms.

Book Description :

Aircraft, wind turbines, or space stations are expected to remain in service well beyond their designed performance lifetime. Consequently, maintenance is an important issue for aircraft or aerospace structures. This is accomplished through inspecting for damage at scheduled times and replacing damaged parts before failure. Ground inspections of aircraft, even using simple nondestructive testing techniques, generally require the aircraft be pulled from operation so that its components can be inspected for damage. Structural components are replaced if sufficient damage is found. Research is underway to develop a structural health monitoring (SHM) system as a means to improve the current maintenance routine. This system would consist of an array of sensors and associated analysis codes which would scan for damage in-flight and perform real-time damage analysis of an aircraft's structure. If damage is recognized long before failure occurs, then a damage tolerance and prognostic assessment could be implemented, allowing for a determination of the remaining life of components. The current method of inspecting aircraft, consisting of ground inspections for damage after a set number of flight hours, works well from an aircraft safety point of view. However, an in-flight SHM system would allow for better use of components, as specific lifetimes could be determined; and, could be less costly, since an SHM system could be embedded into the aircraft structure, thereby reducing or eliminating the need to tear down the aircraft to scan for damage during the ground inspection and would ultimately lead to fewer required ground inspections. General theory for material mechanics, fracture mechanics, waveform theory, and artificial neural networks are presented in this paper. Among these, a simple triangulation method is developed to locate a crack tip position and a procedure of combining the theory of fracture mechanics with waveform theories is introduced. These components were used collectively in a series of experiments to investigate the possibility of using them in a future SHM system. Flat aluminum panels, similar in thickness to those found in many aerospace structures, were subjected to increasing static loading during laboratory tests. As the load increased, a designed crack in the panel increased in size, releasing strain waves into the material. These waves were then detected by acoustic emission sensors, and artificial neural networks were implemented to analyze the received strain waves. From a feed-forward neural network, the crack length was approximated. Next, similar aluminum panels were placed in a simply supported beam configuration with ultrasonic actuators attached at various positions. These actuators created multiple point source locations, which was received by multiple acoustic emission sensors. The location of the source was calculated by both triangulation method and an vi artificial neural network. A theory of plastic zone interference with strain waves released from crack tip extension was introduced and shown as a possibility during the analysis of a final experiment. Sensors placed behind the crack front were observed to detect waves with smaller amplitudes than the sensors placed in locations in front of the crack during crack extension due to increasing, pseudo-static applied load. The effect of the acoustic emission sensor placement relative to crack tip growth detections was determined to be possibly integrated with an artificial neural network in future research. Experiments were conducted to determine the crack length and location, using artificial neural network analyses of acoustic emission signals. Artificial neural networks were developed which were trained with an existing dataset of crack properties. These neural networks were applied to new situations that were not part of the training dataset. The approximated crack growth of the artificial neural networks was around 10% shorter than the actual measured crack growth length for an extension of around 0.8 in. Finally, some SHM analysis systems were proposed, based on the conclusions made in the experiments. The artificial neural networks performed well at approximating both the crack extension and location, using acoustic emission detections. These artificial neural networks in combination with an acoustic emission system are reasonable candidate for the initial stages of a feasible structural health monitoring system to determine the location and severity of structural damage within an aerospace structure.
