Z resonance frequency of your laminated transducer was obtained by a
Z resonance frequency with the laminated transducer was obtained by a graphical technique. The sound field simulation and experimental final results showed that the acquire of the four-stack transducer was 15 dB larger than that with the single-element transducer. An ultrasonic feature scanning program was constructed to realize the qualitative and quantitative detection of the smallest artificial hole (two mm ten mm). Two distinct all-natural defects have been scanned and the outcomes have been compared with those obtained applying an industrial computed tomography detection method. The outcomes showed that the ultrasonic technique was additional precise inside the characterization of two natural defects. The key trigger was that the industrial CT was not sensitive to defects parallel for the incident direction from the ray.2.3. four. 5.The research presented in the paper not just delivers a system for the qualitative and quantitative non-destructive testing of solid propellants, but additionally delivers an important FM4-64 medchemexpress reference for other viscoelastic components.Sensors 2021, 21,21 ofAuthor Contributions: Conceptualization, S.Y. and W.S.; Methodology, Y.C.; Computer software, S.Y. and L.Y.; Validation, L.Y. and M.W.; Formal Analysis, M.W.; Investigation, K.L.; Resources, M.W.; Information Curation, Y.L.; Writing and Original Draft Preparation, S.Y.; Writing and Critique and Editing, S.Y. and M.W.; Visualization, L.Y.; Supervision, Y.C.; Project Administration, S.Y. and M.W.; Funding Acquisition, M.W. and Y.L.
