This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research contributes to the development of an in-situ laser ultrasonic inspection system to ensure a defect-free fabrication of additive manufacturing (AM) parts. AM process is hailed as one of the most innovative technologies of industry 4.0. due to the many unique advantages over the subtractive manufacturing methods. The increased design freedom due to the layer-wise manufacturing also allows significant weight reductions and enhanced component performance with little or no specialized tooling. However, the lack of understanding of the process makes it prone to defects inhibiting its use in safety-critical applications such as power generation and aerospace industries. In the absence of defects, subtle changes in the process parameters can lead to undesired microstructure that can be detrimental to the part performance. Thus, in-situ material state monitoring techniques are urgently needed to realize the full benefits of additive manufacturing. The majority of the current process monitoring systems are vision-based, limiting them from monitoring the internal defects, and are incapable of providing information about the mechanical properties. X-ray computed tomography is being used extensively to detect volumetric AM defects, but it is not amenable for in-situ inspections and is limited by size. Thus, laser ultrasound is considered as a viable solution for in-situ monitoring of AM as it is non-contact and offers benefits of ultrasonic testing, such as detecting volumetric defects and estimating strength-related properties. This research presents a laser ultrasonic system integrated into a directed-energy-deposition additive manufacturing system and demonstrates the in-situ detection of realistic AM defects and microstructural sensing. Laser generation of both narrowband and broadband Rayleigh waves is exploited to detect localized defects created by altering the process parameters in Ti-6Al-4V depositions. Furthermore, the nonlinear waveform distortion of broadband Rayleigh waves is used to detect changes instilled by marginally varying the process parameters for Ti-6Al-4V and IN718 depositions. The AM surface roughness is a key challenge for laser ultrasound-based in-situ monitoring because it affects both wave reception and the Rayleigh wave propagation. Results demonstrate the influence of AM surface roughness and unique microstructure on nonlinear distortions of Rayleigh waves. Furthermore, the capability of the laser ultrasonic system to carry out artificial flaw detection using narrowband and broadband Rayleigh waves and microstructure monitoring using nonlinear distortion of broadband Rayleigh waves is demonstrated for Ti-6Al-4V and IN-718 specimens within the directed energy deposition additive manufacturing chamber.

Book Synopsis Structural Health Monitoring Damage Detection Systems for Aerospace by : Markus G. R. Sause
Download or read book Structural Health Monitoring Damage Detection Systems for Aerospace written by Markus G. R. Sause and published by Springer Nature. This book was released on 2021 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.
Book Synopsis Non-contact Ultrasound by : Xiang Zhang (Ph. D.)
Download or read book Non-contact Ultrasound written by Xiang Zhang (Ph. D.) and published by . This book was released on 2019 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the design, development, and evaluation of two novel non-contact ultrasound imaging methods: immersion ultrasound and optical ultrasound. Immersion ultrasound utilizes traditional piezoelectric elements in a tomographic framework to develop new algorithms and acquisition methods for quantification of tissue geometry and properties in human proximal limbs. Bone is uniquely challenging for ultrasound due to the high impedance mismatch between bone and soft-tissue in the imaging domain. New imaging algorithms are necessary for both geometric and quantitative reconstruction of subjects with bone. Multiple immersion systems were designed and constructed using the framework presented in this thesis. Mechanical systems include a 4 degrees of freedom single element system and a fully flexible 36 degrees of freedom robotic system abbreviated MEDUSA (Mechanically Discrete Ultrasound Scanning Apparatus). An adaptive beamforming algorithm addressing specularity of bone in pulse-echo imaging and a Full Waveform Inversion algorithm for quantitative imaging with bone are discussed, with imaging results on tissue mimicking phantoms, excised animal tissue, and human subjects. Furthermore, a laser ultrasound (LUS) system was developed for full non-contact ultrasound imaging. LUS completely replaces conventional piezoelectric elements for generation and detection of ultrasound in biological tissue. LUS generates ultrasonic waves at the tissue surface via rapid transduction of optical energy to acoustic energy through thermomechanical coupling on the tissue surface and detects returning ultrasonic waves on the tissue surface using laser interferometry. In combination, LUS can utilize any tissue surface as a viable acoustic transmitter or detector. Analysis of light and tissue interactions presented in this thesis identifies the critical process parameters for soft-tissue imaging at eye and skin safe optical exposure levels. LUS system design methods and imaging results on tissue mimicking phantoms, excised tissue, and humans subjects are presented. Human LUS results marks the first instance of full non-contact optical ultrasound imaging of in-vivo human subjects. All systems presented in this thesis were calibrated to ensure safe optical and acoustic exposure levels for human subjects. Approval was obtained from the MIT Committee on the Use of Humans as Experimental Subjects (COUHES) prior to any human experimentation.
