IWSHM 2023 SHM in Action Demonstrator
|After a short video of an airline representative explaining the need to monitor melting ice in aircraft fuel tanks, a device that registers acoustic emissions in the frequency domain will be activated and viewers will be able to see the response of the acoustic equipment to the melting ice. A mini-replica of a section of a fuel tank containing the melting ice will be on display. The ultrasonic signals will be converted into audible sounds.

|The Wireless Integrity Sensor Platform (WISP) uses ultra-low-power miniature SHM hardware to facilitate remote damage detection with minimal cables. When paired with the carbon nanotube (CNT) fatigue crack gauge (FCG), cracks as small as 0.25 mm can be reliably tracked. For this SHMIA demonstration, MDC has built a compact 4-point bending machine to rapidly grow natural fatigue cracks from an EDM notch through repeated enforced displacement. The demonstration will optically show a zoomed-in view of the crack growth, and crack length prediction from the WISP FCG superimposed over the image. During the 5-minute demonstration, we would expect the crack to extend by ~0.5mm.

|Structural Health Monitoring Lab at Princeton University (SHMlab)
|Our presentation will demonstrate the SHM system with embedded fiber-optic long-gauge strain sensors at the Stadium Drive Garage, a five-floor garage at Princeton University. The system can monitor changes in strain, shear strain, curvature, and deformed shape due to environmental factors, such as temperature, and applied loads, such as parked vehicles. Assessment of structural behavior of a complex structural element, double-T beam, will be presented.

|Neuromorphic event-based sampling for energy efficient, high speed, low memory, high sensor count, structural health monitoring We will demonstrate the high speed, yet efficient sampling capabilities of event-based imagers. The success that has been observed with imager-based structural dynamics over the last decade suggests that the real key to enabling practical structural health monitoring systems is to enable the ability to build smart structures with high spatial density sensor networks. This means thinking about creating kilosensor+ count systems. This assertion is supported by the relatively high spatial density of mechanoreceptors found in biological systems. In the past this was problematic on account of manufacturing, power, memory, and computational resource limitations. However, biologically inspired, neuromorphic sensors and computational hardware represent a path forward to make extremely high sensor count, highly responsive, structural heath monitoring systems a reality.

|We wish to demonstrate a smart digital sensor solution that was primarily developed for the aviation industry and optimized using our cross-industry implementation strategy. We wish to start by describing the critical pain-points and how the sensor was selected as a solution for these use-cases. Thereafter we showcase the measurement capabilities of our smart multi-parameter sensing solution using a plexiglass structure excited using a portable shake table, simulating one of our typical use-cases. The information generated from the sensors would thereafter be shown in real-time on our SHM software platform, which could further be used for condition monitoring, analysis and rapid notifications.
|Traditional structural health monitoring methods can be costly and time-consuming, and they often require experts to interpret the data. In this demo, a pan-tilt-zoom camera along with a Jetson Nano is used to automate the process from image capturing to detection and assessment of structural damage. The Jetson Nano will use deep-learning to identify, classify and segment the damaged areas. The severity of the damage can then be determined by measuring the area of the damaged region. This approach can be integrated into mobile vehicles and has the potential to significantly improve the efficiency and accuracy of SHM. It can be used to inspect large structures quickly and easily, and it does not require any specialized expertise.
|Rotary wing vehicle structures require maintenance due to operational requirements, environmental and battle damage, and finite service lives which limits aircraft availability. Structural Health Monitoring (SHM) provides the capability to enable a paradigm shift from schedule-driven maintenance to Condition-Based Maintenance (CBM) of these structures. Sensor networks integrated with structural components provide crucial information regarding the health status and remaining useful life of individual components, as well as the structural integrity of the rotorcraft. Acellent Technologies Inc. will demonstrate the implementation of a SHM crack detection system for aircraft structures. Sensors will be placed on hard-to-access areas such as fittings or similar areas of interest to monitor real-time cracking occurring on the structure. Acellent’s AI based software will process the data and display results to the user to indicate the presence of a crack, its location and size. Data can also be parsed to any onboard HUMS or IVHM system to enable actions related to repair or replacement of the structure. This innovative system is available as a complete kit for users to implement in their rotorcraft or any aircraft structure.
|Missouri University of Science and Technology
|The center for intelligent infrastructure (CII) of Missouri S&T creates, conveys, and applies engineering knowledge and operation intelligence that help solve the world’s increasing challenges with aging infrastructure for a safe, sustainable and resilient community and environment. We wish to demonstrate multi-user collaborative visual inspection of steel bridges using augmented reality technology aided by robots. We anticipate this scenario to be a practical solution for beyond visual line of sight cases using climbing robots.
|This demonstration shows the effectiveness of using edge, fog, and cloud computing technologies in SHM. The data is stored and visualised through a dashboard. It also includes alert system if in case the set threshold is crossed.

|Smart Informax Laboratory at Purdue
|CRAQ is software for the autonomous detection, quantification, and localization of cracks in digital images and/or inspection videos using computer vision and machine learning techniques. CRAQ analyzes the input data and provides a probabilistic report about the existence of cracks and their severity. Once the data is processed, CRAQ visualizes the detected cracks, their quantified characteristics (e.g., crack length, thickness, and orientation), and the confidence levels. CRAQ exports the output results in HTML format that can be used for generating inspection reports by human technicians. CRAQ was originally developed for crack assessment on nuclear power plant reactors; however, its functionality will be extended through the proposed work in this application to monitor other infrastructure systems such as bridges, roads, dams, pipelines, aircraft skin, and wind turbines.
|Structures and Composites Lab (SACL) at Stanford University
|Structures and Composites Lab at Stanford University has developed novel multifunctional energy storage composite (MESC) batteries that can directly be integrated into the structure which carries load. We demonstrated the live electric skateboard where MESC batteries are integrated into the skateboard. We also have the capability to monitor the health state of the MESC battery using ultrasonic signals.
