Processing Ultrasonic Data by Coda Wave Interferometry to Monitor Load Tests of Concrete Beams [PDF]
Sensors, 2018 Ultrasonic transmission measurements have been used for decades to monitor concrete elements, mostly on a laboratory scale. Recently, coda wave interferometry (CWI), a technique adapted from seismology, was introduced to civil engineering experiments. It

Scattering Attenuation of the Martian Interior through Coda Wave Analysis. [PDF]
Bull Seismol Soc Am, 2021 ABSTRACTWe investigate the scattering attenuation characteristics of the Martian crust and uppermost mantle to understand the structure of the Martian interior. We examine the energy decay of the spectral envelopes for 21 high-quality Martian seismic events from sols 128 to 500 of InSight operations. We use the model of Dainty, Toksöz, et al. (1974) to

Impact of temperature and relative humidity variations on coda waves in concrete. [PDF]
Sci Rep, 2023 AbstractThe microstructure of concrete can be affected by many factors, from non-destructive environmental factors through to destructive damage induced by transient stresses. Coda wave interferometry is a technique that is sensitive enough to detect weak changes within concrete by evaluating the ultrasonic signal perturbation compared to a reference ...

Correlation between Coda Wave and Stresses in Uni-Axial Compression Concrete
Applied Sciences, 2018 Stresses in structures are usually converted by measured strains based on corresponding constitutive relations of materials. However, it is difficult to determine the constitutive relation of the material accurately, which leads to significant ...
