Artificial Intelligence-based Structural Health Monitoring



Hui Li
Harbin Institute of Technology (China)

Abstract: On the one hand, it is well-known that the model-based damage detection and model updating are insensitive to minor damage and is impeded due to ill-condition issues. Artificial intelligence includes machine learning, deep learning, computer vision, virtual and augumented realization (VR/AR), etc. Various machine learning and deep learning algorithms provide new potential ways to assess the structural conditions by using the big data, which structural health monitoring systems have sampled. In addition, the computer vision and VR/AR aid us to automatically “see” structure damage directly. In this lecture, the recent advances in artificial intelligence-based structural health monitoring are introduced, including the big data driven-based structural condition assessment, big data and model-based structural safety evaluation, and wind and earthquake disaster management.

Biography: Hui Li is Changjiang Professor in civil engineering and mechanics at Harbin Institute of Technology. Her research interests include artificial intelligence, data science and engineering, structural health monitoring, applied mathematics, fluid dynamics, nonlinear dynamics, and nanomaterials. She is the PI of 15 projects supported by NSFC and the Ministry of Science and Technology, China. She is authors and coauthors of 200 Journal papers and about 80 keynote lectures in conferences.

The Emerging Technologies for Future Space Missions



Fred Hadaegh
Jet Propulsion Lab. (United States)

Abstract: In an age of proliferating technologies, we must innovate and leverage the right ones for the unique challenges of space exploration. For space, technology carries a specific meaning: the means to enable exciting new missions. We have achieved many new capabilities by leveraging technologies that have seen rapid advances for mission applications. For example, the advantages of rapid 3D printing have been pushed to an additional fourth “dimension,” namely by constructing space systems whose functions evolve over the course of the mission. The use of the smart materials has now made it possible to develop gears that no longer require lubrication and will perform in extreme environment for a long time. Other examples include miniaturization of instruments and systems now flying in JPL’s planetary CubeSats, new robotic systems that can crawl on a wall, and the swarms of thousands of tiny autonomous spacecraft. This presentation will provide an overview of the emerging space missions and the breakthrough technologies that will enable these missions over the next two decades.

Biography: Fred Hadaegh joined Jet Propulsion Lab in 1984 after receiving his Ph.D. in electrical engineering from University of Southern California, as well as bachelor’s and master’s degrees in the same subject from the University of Texas, Austin.

Piezoelectric Films for MEMS Applications



Susan Trolier-McKinstry
The Pennsylvania State Univ. (United States)

Abstract: Piezoelectric thin films are of increasing interest in low voltage microelectromechanical systems (MEMS) for sensing, actuation, and energy harvesting. The key figures of merit for actuators and energy harvesting will be discussed, with emphasis on how to achieve these on practical substrates. For example, control of the domain structure of the ferroelectric material allows the energy harvesting figure of merit for the piezoelectric layer to be increased by factors of 4 – 10. To illustrate the functionality of these films, examples of integration into MEMS structures will also be discussed, including adjustable optics for x-ray telescopes, low frequency, and non-resonant piezoelectric energy harvesting devices, and miniaturized ultrasound transducer arrays.

Biography: Susan Trolier-McKinstry is the Steward S. Flaschen Professor of Ceramic Science and Engineering, Professor of Electrical Engineering, and Director of the Nanofabrication facility at the Pennsylvania State University.

Structural Health Monitoring: A View of the Entrepreneur



Tadeusz Uhl
AGH Univ. of Science and Technology (Poland)

Abstract: Nowadays there is pressure for commercialization of research from founding agencies, but the process of commercialization of research needs time and support to be successful because there are several stages and limits which should be crossed to achieve a market product. Some of them are related to technical issues but some are related to business problems. One possible path of commercialization is creating new start-up companies. During this presentation, problems of research commercialization will be listed and discussed. Some case studies related to SHM technology will be presented. Particularly, the talk will focus on active thermography and applications, predictive maintenance based on AI algorithms and its application, on sensors design and application, and some UAV-based solutions.

    Modeling for Research in Ultrasonic NDE



    Michael Lowe
    Imperial College London (United Kingdom)

    Abstract: Research in ultrasonic NDE over the past several decades has been supported by a growing use of specialist modeling tools, to calculate wave propagation behavior, the influences of materials, guided waves, and the scattering of waves from features and defects. Model capabilities are now so good that simulations are being used in a similar manner to experiments, and some important research objectives are not possible at all without them. The NDE research group at Imperial College has worked over many years on the long-term development of some general purpose modeling tools, which have provided essential underpinning to the creation of new capabilities in NDE. This presentation will use some examples of research achievements in NDE to illustrate the vital role of advanced modeling tools in their success.

    Journey From Energy Harvesting and 4D Printing to Medical Applications



    Wei-Hsin Liao
    The Chinese Univ. of Hong Kong (Hong Kong, China)

    Abstract: By utilizing adaptive features, smart materials can be built as sensors and actuators. Energy can be harvested from vibration and human motion. Piezoelectric and electromagnetic power generators were used to transform the mechanical energy from vibration and human motion into electrical energy. On the other hand, robotic exoskeletons that can assist people with impaired mobility have been developed. With the developed device, paralyzed individual can regain the ability to stand up and walk. Smart ankle-foot prostheses with compact cam-spring mechanism have also been implemented to help amputees walk with less effort while having more natural gait. Utilizing additive manufacturing into smart materials has led to 4D printing technology for creating structures that can change their shape and function on-demand and over time. Actuator units were designed and fabricated directly by printing fibers of shape memory polymers in flexible structures. They can serve as tubular stents and grippers for biomedical applications. In this talk, related research projects and key results will be presented.
