Book Description :

Structural Health Monitoring with Piezoelectric Wafer Active Sensors, Second Edition provides an authoritative theoretical and experimental guide to this fast-paced, interdisciplinary area with exciting applications across a range of industries. The book begins with a detailed yet digestible consolidation of the fundamental theory relating to structural health monitoring (SHM). Coverage of fracture and failure basics, relevant piezoelectric material properties, vibration modes in different structures, and different wave types provide all the background needed to understand SHM and apply it to real-world structural challenges. Moving from theory to experimental practice, the book then provides the most comprehensive coverage available on using piezoelectric wafer active sensors (PWAS) to detect and quantify damage in structures. Updates to this edition include circular and straight-crested Lamb waves from first principle, and the interaction between PWAS and Lamb waves in 1-D and 2-D geometries. Effective shear stress is described, and tuning expressions between PWAS and Lamb waves has been extended to cover axisymmetric geometries with a complete Hankel-transform-based derivation. New chapters have been added including hands-on SHM case studies of PWAS stress, strain, vibration, and wave sensing applications, along with new sections covering essential aspects of vibration and wave propagation in axisymmetric geometries. Comprehensive coverage of underlying theory such as piezoelectricity, vibration, and wave propagation alongside experimental techniques Includes step-by-step guidance on the use of piezoelectric wafer active sensors (PWAS) to detect and quantify damage in structures, including clear information on how to interpret sensor signal patterns Updates to this edition include a new chapter on composites and new sections on advances in vibration and wave theory, bringing this established reference in line with the cutting edge in this emerging area

Book Description :

The use of piezoelectric wafer active sensor (PWAS) for structural health monitoring (SHM) has developed into a promising tool for real-time structural damage assessment. The 1-year research work described in this report addresses the following issues: (i) PWAS durability and survivability; (ii) optimum PWAS design; (iii) steering beam large-area coverage (embedded ultrasonic structural radar - EUSR); and (iv) probability of detection (POD) with PWAS probes (an initial investigation). The durability and survivability of the PWAS transducers has been confirmed under various environmental exposures for the duration covered in this one-year effort. These results give confidence in this new technology for installation on realistic structures. The report presents analytical methods and experimental results that can be successfully used in the design of active SHM systems. The EUSR steering beam PWAS phased-arrays method has been refined to increase it power of detection for various structural defects. It has been also proved that EUSR performance is not affected by typical structural curvature. The initial PWAS POD investigation has indicated that crack as small as 1.57 mm can be detected and imaged relatively easily. Overall, the results confirm that PWAS transducers are a technology with good potential for implementation in active SHM systems.

Book Description :

The capability of embedded piezoelectric wafer active sensors (PWAS) to perform in-situ nondestructive evaluation (NDE) is explored. Laboratory tests are used to prove that PWAS can satisfactorily perform Lamb wave transmission and reception. Subsequently, crack detection in an aircraft panel with the pulse echo method is illustrated. For large area scanning, a PWAS phased array is used to create the embedded ultrasonics structural radar (EUSR). Opportunities for implementation into Air Force vehicles and the research needs are also discussed.

Book Description :

Structural health monitoring (SHM) is a major component of the vehicle health monitoring (VHM) concept currently considered for the civilian and military aerospace applications. Piezoelectric wafer active sensors (PWAS) are one of the candidate embedded sensors considered for SHM applications. PWAS are inexpensive, non-intrusive, un-obtrusive, devices that can be used in both active and passive modes. In active mode, PWAS generated Lamb waves that can be used for damage detection through pulse-echo or pitch-catch techniques. An efficient application of the pulse-echo method with PWAS technology is through the phased array technique. In the embedded ultrasonics structural radar (EUSR) concept, an array of closely spaced PWAS is used to detect structural cracks based on the scanning beam principle with guided Lamb waves. A scanning beam of ultrasonic Lamb waves works like "structural radar". When encountering a crack, it generates echoes and backscatter. This concept was initially developed by the authors for guided Lamb waves traveling in flat plates. In this paper, the EUSR concept is extended to cylindrical shells. First, the theory of guided waves in cylindrical shells, with the associated modes and dispersive frequencies is reviewed. It is shown that cylindrical shells accept three types of guided ultrasonic waves: longitudinal, flexural, and torsional. The first and second of these ways can be associated with the Lamb waves in flat plates, while the third can be related to the shear-horizontal guided waves in flat plates. Subsequently, the paper describes validation experiments performed on cylindrical shells of various curvatures. It is shown that the EUSR concept works on cylindrical shells with curvatures representative to actual aircraft structure just as well as it works on flat plates.

Smart sensors are technologies designed to facilitate the monitoring operations. For instance, power consumption can be minimized through on-board processing and smart interrogation algorithms, and state detection enhanced through collaboration between sensor nodes. Applied to structural health monitoring, smart sensors are key enablers of sparse and dense sensor networks capable of monitoring full-scale structures and components. They are also critical in empowering operators with decision making capabilities. The objective of this Special Issue is to generate discussions on the latest advances in research on smart sensing technologies for structural health monitoring applications, with a focus on decision-enabling systems. This Special Issue covers a wide range of related topics such as innovative sensors and sensing technologies for crack, displacement, and sudden event monitoring, sensor optimization, and novel sensor data processing algorithms for damage and defect detection, operational modal analysis, and system identification of a wide variety of structures (bridges, transmission line towers, high-speed trains, masonry light houses, etc.).

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.
