“…With the high frequency range of the EMI techniques, to achieve the precise prediction of impedance responses, the finite element model needs a large number of elements, requiring high computation costs for the numerical simulation. For other piezoelectric wafer active sensor based techniques, such as guided wave methods, more convenient numerical simulation methods, such as the boundary element method (Ge and Chen, 2008), finite difference method (Xu et al, 2003), local interaction simulation approach (Shen and Cesnik, 2016, 2019) and Mass-Spring Lattice Model (Baek and Yim, 2011; Yim and Sohn, 2000), have been developed for the modelling of wave scattering with a reduced computational demand. To improve the computational efficiency, investigations on modelling EMI by making use of the spectral element method (SEM) were carried out.…”

Vibration based structural health monitoring methods are usually dependent on the first several orders of modal information, such as natural frequencies, mode shapes and the related derived features. These information are usually in a low frequency range. These global vibration characteristics may not be sufficiently sensitive to minor structural damage. The alternative non-destructive testing method using piezoelectric transducers, called as electromechanical impedance (EMI) technique, has been developed for more than two decades. Numerous studies on the EMI based structural health monitoring have been carried out based on representing impedance signatures in frequency domain by statistical indicators, which can be used for damage detection. On the other hand, damage quantification and localization remain a great challenge for EMI based methods. Physics-based EMI methods have been developed for quantifying the structural damage, by using the impedance responses and an accurate numerical model. This article provides a comprehensive review of the exciting researches and sorts out these approaches into two categories: data-driven based and physics-based EMI techniques. The merits and limitations of these methods are discussed. In addition, practical issues and research gaps for EMI based structural health monitoring methods are summarized.

The water-squirting ultrasonic detector can not only reduce wetted area of specimen, volume of detection equipment, but also gain longitudinal wave, shear wave, and surface wave detection by changing the ultrasonic incident angle. The paper discusses the development of a new kind of water-squirting ultrasonic detector, which is based on the study of water immersion ultrasonic detector. In this detector, a removable water column replaces the fixed water container for maneuverability; a composited column replaces the water-only column for the ultrasonic coupling channel; a special optimized nozzle is used to form the composited column; an ultrasonic absorption intracavity and an air-water composited mixture are used for anti-interference. Finally, the new kind of water-squiring ultrasonic detector may replace the original water immersion detector, and can be applied to more extensive detection field.
