EBOOK SYNOPSIS:

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.

Structural Health Monitoring Of Aircraft Composite Structures Using Ultrasonic Guided Wave Propagation

ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

"Despite enhancements in terms of specific strength and stiffness by using composite in aircraft structures, their susceptibility to hide damage is still a major point of concern. The objective of this work is to investigate guided wave propagation in composite structures to detect delaminations, disbond and impact damage.The majority of the work focuses on assessment of composite joints. Primarily, a simple composite structure configuration was chosen to evaluate the effect of artificial and real damage on guided wave behaviour. The results show that non-mid-plane artificial delamination can accurately represent real impact, particularly barely visible impact damage (BVID). Next, a composite skin-stringer assembly and a composite scarf repair were chosen in order to represent typical aerospace structural joint features. The reflection, transmission and scattering behaviour of the plane guided waves are studied as a function of mode, frequency, excitation angle and the quality of the joint. For the composite skin-stringer, two inspection strategies are applied. From the first strategy, the within-the-bond, it is concluded that the antisymmetric mode (A0) transmission is highly sensitive to the damage for frequencies below 350 kHz, while the symmetric mode (S0) reflection around 200 kHz could be employed for monitoring an echo induced by the disbond. For imaging the disbond based on the scattering of the waves, the S0 mode appears as the best candidate below 350 kHz, by inducing an increase of 60 % of the scattered field in the presence of a disbond. The results from the second strategy, the across-the-bond, indicate that the A0 mode behaves more directionally while S0 is more refracted, specifically at low frequencies. For damage imaging, the S0 mode appears to be sensitive enough to disbonds (an increase of 30 % of the scattered wave) at around 150 kHz. Comparison of the pristine and damaged repair joint indicates reflection at the tip of each layer in the scarf (the reflections from the steps' edges), which can be an indication for evaluation of the quality of the joint. The anti-symmetric mode in the pulse-echo configuration seems to be an efficient mode and strategy for disbond detection in composite repairs. " --

Release Date: 2012-09-14
Pages: 376
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

The well documented increase in the use of high performance composites as structural materials in aerospace components is continuously raising the demands in terms of dynamic performance, structural integrity, reliable life monitoring systems and adaptive actuating abilities. Current technologies address the above issues separately; material property tailoring and custom design practices aim to the enhancement of dynamic and damage tolerance characteristics, whereas life monitoring and actuation is performed with embedded sensors that may be detrimental to the structural integrity of the component. This publication explores the unique properties of carbon nanotubes (CNT) as an additive in the matrix of Fibre Reinforced Plastics (FRP), for producing structural composites with improved mechanical performance as well as sensing/actuating capabilities. The successful combination of the CNT properties and existing sensing actuating technologies leads to the realization of a multifunctional FRP structure. The current volume presents the state of the art research in this field. The contributions cover all the aspects of the novel composite systems, i.e. modeling from nano to macro scale, enhancement of structural efficiency, dispersion and manufacturing, integral health monitoring abilities, Raman monitoring, as well as the capabilities that ordered carbon nanotube arrays offer in terms of sensing and/or actuating in aerospace composites.
