Numerical simulation of high frequency guided wave testing for anchor bolt defects
Meitan kexue jishu, 2023 Previous research has confirmed that only high-frequency guided waves larger than 1 MHz have the minimum attenuation detection mode for anchor bolt widely used in underground projects.

A Metacoupler for Converting Propagating Waves to Guided Waves in Wire Waveguides
IEEE Photonics Journal, 2017 Propagating electromagnetic waves in free space cannot directly couple to guided waves in waveguides due to momentum mismatch. Here, we propose a method to design a metacoupler that can convert propagating waves into guided waves along wire waveguides in

Defect Detection and Imaging in Composite Structures Using Magnetostrictive Patch Transducers
Sensors, 2023 The use of thin magnetostrictive patches to generate and detect guided waves within the composite samples is investigated for defect detection. This approach has been implemented using SH0 shear horizontal guided waves in both CFRP and GFRP plates.

Elastic Properties Measurement Using Guided Acoustic Waves
Sensors, 2021 Nondestructive evaluation of elastic properties plays a critical role in condition monitoring of thin structures such as sheets, plates or tubes. Recent research has shown that elastic properties of such structures can be determined with remarkable ...

Proceedings of the National Academy of Sciences, 1980 Transversely periodic solitary-wave solutions of the Boussinesq equations (which govern wave propagation in a weakly dispersive, weakly nonlinear physical system) are determined. The solutions for negative dispersion (e.g., gravity waves) are singular and therefore physically unacceptable. The solutions for positive dispersion (e.g., capillary waves or

Managing Complexity, Uncertainty, and Variability in Guided Wave Structural Health Monitoring
SICE Journal of Control, Measurement, and System Integration, 2017 Guided waves are an attractive tool for monitoring large structures. They are able to interrogate sizable areas at once, are sensitive to structural damage, and carry information about the damage location.

Propagation of Waves in Helical Wave Guides [PDF]
Journal of Applied Physics, 1958 The field configuration near the conductors of a helical wave guide is obtained from the solution of the spatial-wave equation for a developed helix. This solution is first obtained for the case of tape conductors and then adapted to elliptical (including circular) conductors by conformal transformation.

Study on Defect Monitoring of Buried Pipelines Based on Piezoelectric Ceramic Transducer
Shiyou jixie, 2022 In order to monitor the defects in buried pipelines accurately,the piezoelectric ceramic transducer was applied to excite longitudinal mode ultrasonic guided waves in buried pipelines.In this paper,the propagation of ultrasonic guided waves in buried ...
