breaking through bottlenecks of guided-ultrasonic-wave-based structural health monitoring: from linear to nonlinear, from distributed to dispersed sensing

主讲人 : 苏众庆

the past two decades have witnessed prosperity in r&d of burgeoning structural health monitoring (shm). however, shm techniques, particular those make use of guided waves, are confronted a few of inherent bottlenecks including the restricted information that conventional linear features can convey, the inefficiency in detecting small-scale damage (e.g., fatigue cracks), and dilemma in striking a compromise between “sensing cost” and “sensing effectiveness”. all these have created a vast barrier towards the real-world deployment of the techniques developed in laboratories. motivated by this, this talk summarizes the efforts dedicated by the research team led by the presenter over the years, with a hope to circumvent these bottlenecks, partially if not completely. in particular, a coated sensor network made of carbon black and pvdf will be introduced, which is able to facilitate in-situ active sensing of ultrasonic elastic waves. innovatively, the sensor network can be deposited onto structures under inspection. such a sensing philosophy retrofits conventional sensor network design, by providing a novel, quick and convenient means to configure a sensor network with quasi-dispersed sensing elements, and circumvents the possible drawbacks associated with the use of distributed sensors (e.g., pzt).
