“…We expect that the PnC-incorporated ultrasonic transducers or sensors can be potentially used for (a) nondestructive testing (e.g. estimation of crack initiation and propagation) for structural health monitoring [65], (b) acoustic emission testing for fault detection and diagnosis of rotating machinery [66], and (c) ultrasonic imaging in medical science [67].…”

Significant prior research has explored elastic wave-energy localization via a defect mode of a phononic crystal (PnC). The integration of defect-introduced PnCs and piezoelectric materials has paved the path for the development of new conceptual products for applications in energy harvesters, wave filters, and ultrasonic sensors. Recently, an attempt has been made to deviate from this paradigm and design an ultrasonic transducer that generates elastic waves. Unfortunately, the previous works have been limited to a single-defect situation. Therefore, as an advanced approach, this work aims to expand the PnC design space into double defects, which will make the ultrasonic transducer useful at several frequencies. As a first step, this study targets longitudinal wave generation. To predict the wave-generation performance, a previous analytical model that was built for energy-harvesting purposes under a single-defect situation is modified to be suitable for the present wave-generation purpose under a double-defect situation. Moreover, two parametric studies are executed to analyze how the output responses change based on changes to the input voltage setting and the spacing between the double defects. We hope that these ultrasonic transducers can be potentially applicable for nondestructive testing in structural health monitoring and ultrasonic imaging in medical science.

“…For the structural health monitoring of solid rocket motor propellants, the traditional health monitoring methods commonly used at present mainly include industrial CT flaw detection, ultrasonic detection method, and X-ray Line photography is equal [3] These methods can achieve non-destructive testing and health assessment of the structure of the drug column, but they are not real-time and can only be measured by regular sampling [4] . For example, although industrial CT flaw detection is highly reliable, it is too inefficient, and the equipment is huge and expensive.…”

Solid rocket motor propellant in the long-term storage process of the drug column structure damage has the characteristics of strong concealment, great harm, and difficulty to detect. At present, for the structural health monitoring technology of solid rocket motor propellant, a large number of studies have been carried out abroad, and related research has been carried out in China. In this paper, the relevant concepts and connotations of solid rocket motor propellant structural health monitoring technology are sorted out, the performance of the main methods of current solid rocket motor propellant health monitoring technology is compared, and the research status of emerging structural health monitoring technologies such as piezoelectric impedance method, fiber grating method and infrared thermal imaging method is analyzed. In this paper, based on the current research status, the possible development direction of future research is explored and prospected.

Concrete is a highly heterogeneous construction material. Waves that propagate through concrete face significant reflection, scattering, and attenuation issues. Understanding the behavior of waves as they propagate through concrete and arrive at a sensor has generated much attention, especially for developing real-world field applications. In this study, a predictive model of attenuated P-wave propagation using Rayleigh damping is presented. The method used frequency excitations ranging from 20 to 200 kHz and smart aggregates (SAs) were embedded in a concrete specimen to excite and receive P-waves. Moreover, 10 distances were marked opposite the exciter at two propagation paths. In the simulations and experiments, signal processing methods were utilized to extract the first arrival packet for calculating amplitude attenuation. The P-wave damping coefficient was modeled using the multi-physical finite element method, and the results of the predictive model were compared with the experimental results. A discussion on the utilization of frequency-dependent attenuation coefficients was conducted to explore potential P-wave attenuation factors and their respective contributions to the overall attenuation. Numerical studies have demonstrated a strong correlation with the experiments when an appropriate level of material damping coefficient was considered. By enhancing the overall comprehension of the P-wave damping coefficient and attenuation characteristics within concrete, damage detection techniques based on P-waves can be improved.
